IPv6 ASN question

Hi Harold,
We were just issued our IPv6 address block by Arin, and it came with three ASNs. Could you provide any information on why there are three (instead of just one)?  Also, would I use one of those ASNs for my EIGRP routing on the inside or are those only for use with my BGP routing to our ISPs? (in other words, can I use a private ASN for EIGRP on the inside or will that mess things up?) Thanks much!

EIGRP AS number isn't related to BGP AS number.  As a general rule, to communicate with other ISPs via BGP you need a public AS number given to you by someone like arin.  You can pick whatever AS number you like to use for EIGRP.  Your EIGRP AS number has no bearing whatsoever on your BGP AS number.  They can be the same, or they can be different.

  • IPv6 address questions

    I'm having trouble understanding IPv6 addresses. In IPv4 the CIDR slash notation means what subnet the address is in. But a /48 in IPv6 does not mean subnet. I have no idea what it means. For instance I've seen the address 2001:0:1:5::1/64, and I have no idea what the /64 means. Can someone explain it?
    Link local address: it's not enough to put an FE80 to identify this kind of address, but for some reason, they decided to put FFFE in the middle of the ipv6 address. What were they thinking? Why do they need to identify this kind of address TWICE within the address, AND why couldn't they put the FFFE at the end or the beginning, but instead they put it right in the middle? WTF?
    3 types of addresses? What why? with that many bits in an address there's no reason to have 3 of them. Theres enough for everyone.
    Illogical allocation of bits. A global ip address reserves the last 64 bits for the host ip. This is equivalent to 18 quintillion hosts on ONE SUBNET! YEAH RIGHT! There's no way that's even remotely logical, feasible, or practical. The more I look at IPv6 notation, the more I think my 5th grader could have come up with a better design.
    Also, why didn't they adopt the OSI model of addressing, like in ISIS. That has more than enough addresses for everyone.
    Obviously i'm missing the point completely on IPv6. It sounds like the most unthoughtful pile of rubbish ever conceived. So can someone please direct me to a place or explain what the thought process was when creating this new addressing scheme?
    bonus points: what happened to ipv5, and what was ipv1,ipv2,ipv3? I think the inventor should have called it IPv2000, because he really went overboard.

    Hi Richee,
    ISPs generally give ipv6 addresses to companies with /48 prefix length.
    The company receiving this can create its own subnets within the /48 and /64 range.
    The last 64 for bits of the address are generally used to insert the mac-address of the local interface when using stateless auto-configuration, but you can use it for subnetting as well, if you configure your addresses manually.
    For the other questions I think this link could give you more info:
    http://www.cisco.com/en/US/tech/tk872/tsd_technology_support_protocol_home.html
    And one more little addition:
    Nothing is perfect in this universe. Everything can be considered good or bad, it is just a question of viewpoint.
    Try to look at ipv6 from both viewpoints. You will have surprises.

  • IPv6 DNS Questions with DirectAccess

    Hey,
    I'm hoping someone can answer some fundamental questions that I am having around DirectAccess for a customer that I'm working with.  We are putting in Direct Access with a more complicated scenario, but there are some fundamental questions about IPv6
    that I cannot quite get answered.  We have the tunnel established over IPHTTPS, however, I am not able to resolve internal resources.
    We have a red x next to the DNS Monitoring in the Operations Console.  DNS64 is green. 
    1) I know that you don't need IPv6 on our internal servers to use DirectAccess.  However, in this situation they have IPv6 unbound from the NICs on all the servers except for the DA server (and the Windows 7 clients).
    2) Brings me to the DNS question.  Internal DNS servers do not have IPv6 bound to the NIC and they do not register AAAA records in DNS.  Does that pose any issues with the NRPT?
    Thanks for your help!
    Bob

    Hello,
    After talking with Microsoft support here was the actual issue.
    First, the issue around the DNS going red:
    Set-DAClientDnsConfiguration -DnsSuffix '.internal.company.com' -DnsIPAddress @('ipv6 address of the DA server') -Verbose -ComputerName 'DAServer.internal.company.com’
    That fixed that issue, however, we were still having issues with the routing to internal servers. 
    We did the following further troubleshooting with Microsoft,
    We checked if client was able to get to the IPv6 address of the server – failed
    Checked if the client was able to get to the IPHTTPS address of the server – worked
    On the DA server itself, we were unable to ping the IPv6 address of the server      (fd58:c2f1:4a56:5555::1). We tried pinging this IP address using the IPHTTPS address on the DA server and that failed
    as well.
    Since we were unable to get to the IP address on the server itself, we just removed and re-added      the IPv6 address of the server, on the Internal NIC, and we were then able to ping the server’s IPv6
    address.
    But, clients were still unable to connect.
    So we realized that the forwarding must have not been enabled on the NICs.
    We checked for Forwarding being enabled on the IPHTTPS and Internal interface of the DA server
    and found that this was not enabled on the Internal interface.
    Once we enabled this, client machine was then able to connect to internal resources over Direct Access.
    To enable forwarding on the NIC we ran the below command,
    netsh int ipv6 set int <interface_id> forwarding=enabled
    Thanks,
    Bob

  • IPv6 - Newb Question (BGP Advertisement)

    Hi Everyone - Quick question on IPv6 subnetting
    If we are allocated a /32 from an RIR (eg 2001:0DB0::/32), and we advertise the /32 to our upstream Inet providers - Assigning
    2001:0DB0:0:10::1/64 to a loop Interface, we *should* be able to reach the Upstream providers IPv6 addresses with a source of the loop interface(As the /64 is within the /32 subnet)?
    Cheers.

    Hi John,
    Correct. You should be able to use that technique to perform initial testing for your ipv6 connectivity. You can use extended ping for instance to specify the loopback interface as the source address.
    Regards

  • IPv6 address question

    Good morning everyone,
    I need to find this address:
    fe80::404d:9415:115a:f39c
    It looks like a link local address.  But there is no ffee inserted between the 6th and 10th bits where the mac address would be inserted.  Can I find the mac address from this IP address?
    Thanks
    Shane

    If the address is being seen on a span port, your best bet might be snooping ICMPv6 neighbor solicitation packets with that address as the source.  It's probably a windows-7 box somewhere; other vendors such as Apple or Linux tend to use the EUI-64 mappings on their link-local addresses.   In an Active Directory environment you can use group policy to discourage use of v6 privacy addresses by windows systems.
    Depending on your DNS infrastructure, the dual-stack (presumably) box might be registering 6to4 or other AAAA records.   The 6to4 case is only likely if it's IPv4 address is public, rather than rfc-1918 private.
    For SNMP, I shouldn't have said ports; you want the MIB that lets you query the neighbor discovery table of whatever is doing the vlan routing; be that a switch, firewall, or an actual router.
    An example of a European university doing this sort of monitoring is described at:
      http://www.terena.org/activities/campus-bp/pdf/gn3-na3-t4-cbpd132.pdf
    FYI, if you have dual-stack devices on your network, I presume you are filtering for rogue RA devices and rogue DHCPv6 servers, e.g. on our client switchs we define:
    ip access-list extended v4client
    deny   udp any eq bootps any eq bootpc
    deny   icmp any any redirect
    permit ip any any
    ipv6 access-list v6client
      deny udp any eq 547 any eq 546
      deny icmp any any router-advertisement
      deny icmp any any redirect
      permit ipv6 any any
    and then on the client device interface switchports we filter:
    ip access-group v4client in
    ipv6 traffic-filter v6client in
    This requires v6 allocations in the TCAM of course, e.g.
       sdm prefer dual-ipv4-and-ipv6 default

  • IPv4 vs. IPv6 programming question

    I have a machine that I believe is running only IPv6 and here is why, when I try to compile and run this example I found on the internet:
    import java.net.*;
    import java.io.*;
    public class ip
    public static void main ( String[] args ) throws IOException

    System.out.print("Host name: ");
    hostname = input.readLine();
    try

    System.out.println("IP address: " + ipaddress.getHostAddress());
    catch ( UnknownHostException e )
    System.out.println("Could not find IP address for: " + hostname);
    When I run the example and type in liveupdate.symantec.com I get this from the program:
    Host name: liveupdate.symantec.com
    Could not find IP address for: liveupdate.symantec.com

  • IPv6 config question

    What am I missing? If I leave my network 10.5.5 configuration in it's default (automatic) mode the net interface is configured as
    inet6 fe80::21e:c2ff:fe15:f0f6%en0 prefixlen 64 scopeid 0x4
    My system will not respond to neighbor solicitation from another host. If I configure the IPv6 router, address, and prefix manually then ifconfig shows NO v6 configuration. The only way to get ipv6 to work is apparently to manually ifconfig the interface, in my case using
    ifconfig en0 inet6 alias ipv6-address-goes-here/64
    I'm sure I'm doing something wrong.... but what? If a manual ifconfig is necessary where is the best place to put it so the command will be run whenever the box is rebooted.
    Thanks for any advice.

  • Basic IPV6 setup question

    I am experimenting with IPV6 and have three devices in my test network.  They are setup as follows:
    UC520 using BVI:   FD:0:0:1::1/64

    The Windows servers can ping each other, the Cisco can ping itself.  However I can't get pings from either Windows server to the Cisco.  I also tried pinging the Cisco using link-local IP but that doesn't work either.  Seems like I am missing something very basic, or so I hope.

  • IPv6 Support Question

    I'm trying to run a small Android app which requires link-local IPv6 communication over a WiFi link. Unfortunately, my BB Z10 seems to ignore IPv6 settings of the network device.
    I have enabled IPv6 support for the WiFi link, but in the advanced network view I don't see any IPv6 address.
    Trying to use ping with IPv6 results in an error message showing the available command line options of the ping6 utility. Any suggestions how to get this work?
    My OS version is 10.2.1.2141.

    No. Usually the ISP will assign you an IPv6 prefix which you can use in your LAN. You will still need a router. More than ever. Only instead of assigning private IP addresses in your LAN you can assign public IP addresses to your devices, i.e. you don't need NAT anymore.
    Anything else would make networking much more complicated. Just image you have a few dozen random IPv6 assigned directly by your ISP (i.e. a few dozen active internet connections). The ISP must keep track of each IPv6 address. And for your LAN network you must also know what is in your LAN and what not. It could well be the the IPv6 address of your printer today is assigned to somebody else tomorrow..

  • IPv6 Summarization Question

    Hi,
    reading the book on ROUTE exam 642-902 I hit upon the following. Page 774 and Page 780
    There are 3 Loopbacks on a router with following addresses:
    3:1::/64
    3:2::/64
    3:3::/64
    The author (page 780) decides to summarise these into 3::/16
    I would have summarised as follows:
    3:1::/64  = 0003:0001::/64   0003:00000000 0000 0001::/64
    3:2::/64  = 0003:0002::/64   0003:00000000 0000 0010::/64
    3:3::/64  = 0003:0003::/64   0003:00000000 0000 0011::/64
    These subnets are thus bit-equal up to and including bit nr 16+8 +4+2 = 30
    I would have summarised as 3::/30
    Am I missing something?
    Thanks
    Fred

    Yes, you are correct and aren't missing anything.  The author was a bit "sloppy" summarizing subnets that aren't actually in the aggregate.
    The author's aggregate summarizes:
    3::
    3:ffff:ffff:ffff:ffff:ffff:ffff:ffff
    A bit more than just 3:1::, 3:2:: and 3:3::.
    Likewise, your example is a bit overreaching - technically.
    Your aggregate summarizes:
    3:0::
    3:1::
    3:2::
    3:3::
    Perhaps:
    3:1::/64
    3:2::/31
    is more "technically" correct.
    I've been using /128's for loopback addresses all carved from a single /64.  Just another way to do it.
    cheers.

  • Configure IPv6 ACL Extensions for Hop by Hop Filtering

    I have IPv6 ACL questions and concerns.  The following code is an example:
    ipv6  access-list inbound-to-enclave
         remark block IPv6 DO Invalid Options
          deny 60 any any dest-option-type 5
         deny 60 any any dest-option-type 194
         deny 60 any any dest-option-type 195
    I see that dest-option-type became available in IOS release 12.4(2)T.  I can't tell if this option was added to later releases of 12.2.  Also, is it available in all releases of 15.x.
    I am guessing that if a version of the IOS that is used is prior to 12.4(2)T that the default action will be to pass this traffic, correct?  Thank you for any assistance that you can provide.

    Hi Forrest,
    This is correct. By default, this traffic would be allowed.

  • Message not being delivered.

    i'm working in my test lab system.
    I have 2008 DC with Exchange 2007, 2010 and now 2013.
    before installing the 2013 message delivery between 2007 and 2010 worked without issues.
    however after installing 2013 message delivery between 2010 to 2007 stopped. 2013 to itself fails. 2007 to 2010 works but not to 2013.
    i'm struggling to find all possible causes and solutions. I can't work out all of the 2013 changes to message tracking yet but the 2010 message tracking shows that the ip address of the servers are ipv6. as of yet I have not configured any ipv6 addresses
    so maybe this is part of the problem or not. i'm trying to deal with the message delivery issue and also look into *how to step-by-step* configure ipv6 too.
    question 1: what do I need to look into the issue of the Exchange message delivery failures. then I will have to look into setup ipv6 properly.

    Hi,
    According to your description,the mail flow issue may be related to the lost AD object "First Administrative Group". Thus,let's firstly try to restore the object by Active Directory Administrative Center. And here is a reference you can refer to:
    http://blogs.technet.com/b/canitpro/archive/2013/04/11/step-by-step-utilizing-active-directory-recycle-bin-to-restore-a-deleted-object.aspx
    Additionally, for the mail flow issue, we can try the basic troubleshooting method to narrow down the cause.
    1. Check if all transport services are working properly and we can try to restart them to have a test.
    2. Check the mailflow with Telnet and confirm the basic error code.
    Thanks,

  • EA6900 Update and Two Suggestions for Future Firmware "Nice to Haves"

    Hey, first off, I've been a user of Linksys Routers for many years now, so I am familiar with the different settings and other selections that you generally see on the firmware pages.  As to the EA6900, I am very, very PLEASED with how this router initially set up, along with the different pages in it's firmware.  With the one exception noted below, the pages and the various settings "flow" very well.  This baby is up and kickin and the house is literally dripping in both 2.4 and 5 GHz RF.  The DHCP Reservation and MAC Wireless Filtering Tables worked without a hitch.  The setup for FTP and NAS was simple!  BTW, the setup for FTP shares is far easier than what we had to do using the EA3000 firmware.  Kudos there!  I am using the router associated with a server that is hosting about 25 different wired devices throughout the house, with a Cisco SG-200-08 Smart Switch behind the router for the LAN, which is load balancing on a Teamed (2 NIC'S) 2GB Adapter .  The router grabbed Comcast's Native IPv6 and set that up flawlessly.  Here is the information on how all that went (read from the bottom up): http://www.dslreports.com/forum/r28693387-IPv6-Dumb-Questions-About-My-IPv6-Goat-Roped-Hookup  Information on how the netwrk worked in Teaming  and LAG mode is here: https://supportforums.cisco.com/message/4071888#4071888
    OK:, So, Mr. Linksys Firmware Developer, whoever and wherever you are, I have two suggestions on the user GUI that would make everyone's life a little easier next time the firmware is updated:
    1.  Please make it so numbers, particularly MAC and IPv6 numbers, can be copied and then pasted to another place in the firmware.  For example, in the Information tab of the Device Settings section, I should be able to copy MAC and IP numbers and then be able to paste them, say, in the DHCP Reservation Table. Other Linksys device firmware allowed for this.
    2.  For goodness sakes, PLEASE don't nest the Diagnostics tab under the Troubleshooting group.  It drives me nuts to think that getting the router's status, to ping or traceroute, or to do a firmware backup would be found in "Troubleshooting".  Suggest that all y'all just remove the Diagnostics tab to the far left side of the application and have that item as its own stand-alone group!
    Then I will be most happy.  As if it really matters, BUT I wanted to give all y'all my perspective from a user way down in the day-to-day weeds. A most happy Boy otherwise.

  • IPv6 Address Management and Security Questions

    I'm trying to draft an IPv6-based version of our location's current routing configuration in anticipation of when our ISP will finally roll it out, and address management has been giving me the biggest headache - ironic, considering IPv6 was supposed to simplify address allocation.
    My first config draft was made assuming that I would be getting a static /56 or /60 prefix from the ISP, and I was just going to insert the prefix into my DHCP pools and there would be no issues. That was before reading around and discovering that some ISPs are considering prefix delegation (PD) for both residential and business accounts instead of static blocks. Now I have questions about how to stick as close to the current IPv4 configuration as possible.
    For the PD scenario, what I am looking at now are two addresses ranges for each network - a ULA /120 space that I want to control using stateful DHCPv6, and the global space which can be /64 and auto-configured. That way there will be a "private" address space for internal routing in the event of a prefix change or an extended outage. But I'm not sure how the config should look for such a scenario. What I have drafted so far is this:
    ipv6 dhcp pool DHCP6_INTERNAL
     address prefix FDAB::1:0/120
     domain-name whatever.net
     dns-server FDAB::1:1
    ipv6 dhcp pool DHCP6_DMZ-WIFI

    Will this config work? By which I mean: will the DHCPv6 servers provide ULA addresses, and will SLAAC work for global address allocation? If not, what needs to be changed?
    Also, another question. I found a few references to a prefix name (the "ISP-PREFIX") which can be used as part of a static IPv6 address on an interface, which is a good idea in case the prefix changes. But that brings up another concern - if the prefix changes, that will invalidate ACLs referencing the global addresses using the previous prefix. Is there anything similar to the prefix name string that can be used in ACLs to keep this from occurring?

    DHCPv6-PD is not necessarily dynamic the same way as DHCP was with the public IPv4 addresses in the IPv4 world.
    While the outside network (PPPoE, DHCPv6, anything) might be truly dynamic and changing with possibly every login session, the DHCPv6 delegated prefix might be tied to your login credentials or DHCPv6 client's DUID after the first connection. A bit like a DHCP lease reservation.
    If that is the case, there is some possibility that your ISP will run reverse route injection, and will always route your "fixed" prefix  to the currently active dynamic "outside" address.
    Talk to your ISP and have them confirm that, once the PD'd /48 or /56 is initially assigned, it won't change, and that the same prefix will be delegated every time. Then you can treat it as if it were fully static, and you won't have to go down the ULA path.
    I contacted one of our local ISPs, and they're doing it exactly that way: PPPoE for IPv4 and IPv6 (fully dynamic), and DHCPv6-PD with the /48 tied to the PPPoE login credentials. I might change to that ISP sooner or later.
    With my current ISP, my IPv6 access is 6RD based. I get a /60, with my current public ipv4 address (by DHCP) embedded into those 60 bits. Readressing is bound to happen sooner or later, and it happens every so often, and it breaks my IPv6 ACLs.
    I'm also looking for a way to write IPv6 ACLs with wildcard bits, not prefix/mask, so I can use them with ZBFW. So far, no sign of it.
    A few more comments:
    ULA addressing: 
    It may look tempting, plausible and intuitive to use dual global and ULA addressing. 
    I started this way as well. However, it turns out that Windows 7 has (had?) some issues with proper source address selection. The "longest common prefix" rule never seemed to work properly. In some cases, it would pick the global address to talk to ULA hosts, or stubbornly insist to use the ULA address to talk to an IPv6 internet host. It was a frustrating experience. Be sure to test this to the full extent (and back, and again and then some more) with every operating system you intend to use.
    Using /120:
    Be sure to test this as well, and very thoroughly. Subnet masks longer than /64 are sometimes called "uncharted territory" in IPv6. Longer subnet masks will break SLAAC, and there may be (embedded) devices that will not react benevolently to a subnet mask other than /64, or simply lack support for DHCPv6.
    adjust-mss
    I see you have "ip tcp adjust-mss 1300". While PMTUd may be mandatory with IPv6, I found it being broken already :-( . "ipv6 tcp adjust-mss .... " is now a separate command since IOS 15.4(1). I would suggest considering it, depending with your experience with PMTUd on IPv6.

  • Question about Oracle10g Net Services'IPv6 Support

    I'm working in a network group which is studying the IPv6.Recently I installed oracle10g in the RedHat Linux-9(kernel-2.4.22,which supported the IPv4/IPv6 dual mode),but I can't configure the oracle10g in IPv6.
    I tried every method to find the solution,including read the oracle10g document,use the google,ask the support service,but there was no answer.And I can't login into the metlink to ask question because I didn't have the CSI number.
    So who can give me some advice about the configuration.Thank you very muck!

    I read the document before it was taken down a couple weeks ago. It said that IPv6 support would be introduced with Oracle11g and not back ported.
    Kind regards,
