BGP ipv6 Implementation
We started to test dual-stack bgp implementation. although we established neighbour over ipv6, seems still we couldnt advertise our networks on internet and we couldnt reach anywhere over ipv6 address.
Here our related configs and outputs;

What we supposed to do ?
Best regards.
Yes, we have three C class networks and one of them is used for firewall side.
May i ask aother question?
On ipv4 bgp conf. we use route maps for coming and outgoing traffic on 3 different metro ethernet internet connections. We have 3 c class ipv4. so we configured load sharing for each networks between net connections. We use local-pref, weight or as path prepend.
Could we do the same thing for ipv6 connections ? We have ::/48 . for example we want to use ::/56 and share networks on internet lines.
Best regards

IPv6 implementation on WLC ( 7.2.103) along with ISE
Has any one done the ipv6 implementation on Wireless Network with user Authentication for guest access using ISE 1.1.
My customer has following componets in the wireless network .
1. WLC 5508 with 7.2.103 version
2. ISE 1.1
Please forward the steps required for integrating ISE as CWA guest portal for ipv6 .The Cisco Identity Services Engine, Release 1.1, is not compliant with IPv6.

"sh ip bgp ipv6" or "sh bgp ipv6"
Hi All,
im trying to clarify some confusion with where this is going in terms of show commands for bgp
when i first played with ipv6 bgp in 12.3 years back, the only way to view bgp v6 items was via "sh bgp ipv6", and this as far as i recall was meant to be the way forward for v4 too, and 'sh ip bgp' was to be removed in future ios releases.
Now im looking at SRE5 in the lab, and a 'sh bgp ipv6' gives me not output saying its deprecated, and 'show ip bgp ipv4' shows me all v4 and v6 bgp neighbour sessions.
if anyone can anyone shed some light on this it would be great since its a tad confusing, even more when you add vpnv4 to the mix.
thanks
MarkMark,
Let me try to answer your question like this.
As far as I know. Both commands are still valid (check int recent 15.2.1T release).

What is deprecated is the command without "unicast" added.
R2#show ip bgp ipv6% Incomplete command.R2#show bgp ipv6BGP table version is 3, local router ID is 192.168.23.2Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale, m multipath, b backup-path, x best-external, f RT-FilterOrigin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path*> 2001:DB8:2::/64 :: 0 32768 i% NOTE: This command is deprecated.

I'm not aware of anything specific to SRE that would cause it to be different.
Can you make share same outputs from your devices?

Hi,
does anybody here have a practical experience with IPv6 implementing within a big corporate network?
Let's say the corporate has got several thousands of sites, some of them in Europe, others in Asia and Americas.
20 Data Centers are used for the Internet connectivity.
So what kind of IPv6 addresses should it use?
As all IPv6 documents are saying "Don't think about ULA and NAT, use GUA!", it should try to get PI (Provider Independent) addresses, I guess?
Looking to RIPE web pages (http://www.ripe.net/ripe/docs/ripe-452) I found only an info it's necessary to have a contract with a LIR to get some PI addresses but no details :-(
How big could such a block be? /32?
But is it possible to use one PI address block worldwide?
I don't think so, as ISPs in America would not accept prefixes provided by RIPE, I'm afraid?
So the corporate should try to get a PI block from each RIR (RIPE, APNIC, ARIN, ...)?
Even then with /32 PI per continent available, it would be necessary to advertise only some more specific subnet from each DC probably?
Let's say /36?
But would /36 be accepted by the ISPs connecting the DCs to the Internet?
And propagated to the neighboring ASes?
I've been told /32 is the maximum prefix length accepted? (But using an IPv6 looking glass I can see lots of /48s among the current IPv6 BGP prefixes within the Internet?).
So it would be necessary to use a single ISP per continent?
Even when all mentioned above would work, it would be necessary to advertise the default route into the corporate network a very sophisticated way to ensure all /36 clients would use the correct DC to enter the Internet to avoid an asymmetric routing!
So I'd really like to discuss with somebody who fixed all the issues listed above already!
Thanks,
MilanHi Milan,
I Did get a chance to be a member of deployment of such network for a customer ,and he had multiple AS as well as IPv6 addresses from RIRs .The RIRs are willing to give a /32 without much concern based upon simple justifications.The equivalent of a /24 IPv4 being advertised to the internet is a /48 in IPv6 world (This is the lowest any enterprise would get).
Regarding the inter-connectivity between the various sites and the path to the internet via the DC ,it would depend upon the architecture you have in mind.I mean if you have a Service provider MPLS backbone,provider independent inter-connectivity over the internet.
We used service provider backbone with multiple layers of route reflectors connectivity from the DCs to the sites and then diverting traffic to the nearest site.
However we could discuss in detail what exact scenario lies for your case. -

Neighbour configuration should be done under router mode, then you activate per neighbour under address-family ipv6. -
Firmware upgrade for WRT120N to support IPV6?
IPV4 IP addresses will be running out in less than a year and I wanted to know, will there be a firmware update for WRT120N to support IPV6?
If not, why?
Also, if I have to buy another router to support IPV6, I'm going to buy a D-Link. It's nothing personal, I just find it absolutely idiotic that a router that supports wireless-N doesn't support IPV6. You have to ask your self, how does the standard IPV6 spec thats a few years old not make it to the final product of a router, but a non-standard wireless-N spec implementation somehow got the O.K....?If you want to know about a firmware update you have to call Linksys support. You won't get an official answer here.
It's absolutely not ridiculous. Maybe IPv6 implementations are around for a while. But it was mostly basic routing and connectivity. All major companies only started maybe two or three years ago to fully support IPv6 in their pro devices. Before that, IPv6 was usually an update not included in the base firmwares. Often it was a paid option. And even today you'll find IPv6 not really equally supported in high-end firewalls which is why some companies are even now reluctant to deploy IPv6 because they are afraid to weaken their firewalls...
And you write yourself: your provider is testing IPv6 now. Isn't that ridiculous, too?
And even today you'll find many client devices in stores which don't at all support IPv6, yet, for instance printers, VoIP phones...
Thus which consumer brand do you think is so much more trustful? And to work perfectly on an Internet connection where even your ISP is still in test phase? -
Hi,
I wanted to deploy IPv6 services on my all webservers m not having idea to deploy IPv6 on web servers like IIS or Apache .
Could someone help me into this concern.Hi Nick,
cheers for the response.
We've been running ipv6 capable smtp servers for the past three years and have had ipv6 implemented across the rest of our infrastructure since 2003.
While I appreciate that ipv6 users may be in the minority at the moment that situation will change over the next few years.
One of the reasons that we went with Ironport was the fact that we were told
that v6 would be implemented in Q4 '08.
Just wondering if this is likely to happen in the foreseeable future.

IPv6 traffic inspection on AIP SSM20
Hi fellas!
I'm a little confused. It says that for the ASA AIP SSM-20 it has ipv6 support. Yet when I look for how to do it, it says that the ASA's Modular Policy Framework does not support ipv6. Any bright ideas on this one?

Getting ipv4 loop-back address on a pure ipv6 solaris machine
import java.net.*;
public class x {
public static void main (String [] args) {
try {
//System.setProperty("java.net.preferIPv4Stack", "false");
//InetAddress ia= InetAddress.getByName("::1");
InetAddress ia= InetAddress.getByName(null);
//InetAddress ia= InetAddress.getLocalHost();
System.out.println(ia.getHostName());
System.out.println(ia.getHostAddress());
ServerSocket ss= null;
ss = new ServerSocket(7833,1,ia);
} catch(Exception e){
e.printStackTrace();
The above program generates the following exception.
Machine: pure ipv6
OS : SunOS uni6505l1-sun1 5.10 Generic sun4u sparc SUNW,Sun-Fire-V440

Actually this is a part of my bigger problem with Tomcat6, which tries to listen on hard-coded ipv4 loop-back address for its shutdown port. As my machine is pure IPv6, or at least has above configuration, it fails to create a socket on 127.0.0.1, but, the above program returns me a 127.0.0.1 if I call InetAddress.getByName(null).
My question is, why is it returning 127.0.0.1, when I never had it as my loop-back address, I had ::1 configured.
Thanks,Accoridng to my expereince, JDK 5/6 maybe uses 127.0.0.1 when creating the serversocket.
I tried it on a Windows 2008 RC box. If I disable the IPv4 by "netsh interface ipv4 uninstall" so that "127.0.0.1" is not accessible, I can not create the ServerSocket any more.
However, If I disable the IPv4 by unchecking the IPv4 stack in the network property so that "127.0.0.1" is still accessible, the Serversocket can work for me.
You can try to enable the "127.0.0.1" on your Sun box and run your code again.
I also find that this issue may be fixed in JDK 7 beta. You can also try the JDK 7 beta with your code.
http://bugs.sun.com/view_bug.do?bug_id=6379550
It is known that JDK 5/6 has big issues on Windows Vista/2008 because of the IPv6 implementation. I am wondering whether Sun OS has the similar problem. -
I have a EBGP-peering connecting two AS with both address-family ipv4 and ipv6 but the prefixes advertized from each AS does get dropped by the other end of the session by local policy:
"MP_REACH NEXT_HOP Martian: n/a 2239"
The BGP session is set up between the IPv4 addresses on the link.
What does this message in "sh ip bgp ipv6 unicast neighbors" mean? Why isn?t the IPv6 prefixes accepted?The impact of running two sessions is obviously that you will consume more resources on the box. It might not make a difference if you only have a handful of peers.
One more thing to remember. If you are going to use the v4 session to carry v6 prefixes between iBGP peers, you will need to explicitly set the v6 NH using a route-map. Otherwise, the NH will be the v4 of the iBGP peer and it will not work.
As for best practices, in my experience, people are most of the time using a v6 session to carry v6 updates.
Hope this helps, -
I am bewildered to see that the first posting about the need for IPv6 support in Linksys routers was made in August of 2006. It is now April 2010, and there is still very little (if any) support for IPv6 in Linksys routers.
In case nobody was paying attention--the IPv4 address space will be exhausted next year! Heelloo--wake up!
We need robust IPv6 implementation support now if we're going to have our app's ready to go when there will be no alternative.Comcast starts trial testing of IPv6 with customers in June. It's time to stop putting it off and get IPv6 support into the firmware.

The working connection between two cisco routers doesn't show any output

IPv6 in Merlin (JDK 1.4)
Hi there
I have tried to play with the IPv6 implementation of Java 1.4
Well, it works, locally.
As soon as I try to establish remote, nothin happens, even no exception or error.
I use Win2k with a protocol stack developed at University of Lancaster.
The IPv6 address I try to use is 2000::102.
Are there any hints?
Thanks
BjoernWhen you say IPv6 on Windows 2000 I assume you mean the research/preview seperate stack implementation - this is not supported by J2SE 1.4. In order to test with IPv6 you need to use Linux (rebuild kernel to include IPv6), or Solaris 8.
