Address-family ipv4
Hi,
I want to understand VPNV4 and IPV4 address family.
when looking our PE router under the VPNV4 address family we have 4 commands
address-family vpnv4
neighbor partial-table send-community both
neighbor 1.1.1.1 activate
neighbor 2.2.2.2 activate
neighbor 3.3.3.3 activate
The address’s above are our route reflectors obviously on different ip’s
Do you need this command to bring up the IPV4 address family? so the first thing to do is create your address-family vpnv4 then your IPV4 address family?
Hi James,
There are multiple options available when you configure BGP on cisco routers.
(config-router)#address-family ?
ipv4 Address family
ipv6 Address family
nsap Address family
vpnv4 Address family
More options on new codes---
IPV4 is for V4 address,IPv6 for V6 address and VPN4 is to carry VPN routes when using MPLS. This is basically gives you more options to manage bgp configuration. By default all the neighbors under address family are disabled hence activate command is required.
You can define yours neighbors under normal BGP process with no bgp default ipv4-unicast which will disable default behavior of IOS to exchange IPV4 routes and later on you can activate that neighbor in address family you want to use for route exchange.
Thanks

Address family vpn4/ipv4 for EBGP
What is the difference between "address family vpnv4" and address family ipv4", do I have to configure both for an EBGP session ?
Thanks
NKVPNv4 is used for the support of MPLS VPN as described by draft-ietf-l3vpn-rfc2547bis-03.
http://www.ietf.org/internet-drafts/draft-ietf-l3vpn-rfc2547bis-03.txt
IPv4 is for the support of regular ipv4 addresses.
You may need to enable vpnv4 or/and ipv4 depending on what you want to do.

Difference between address-family ipv6 and address-family ipv6 labeled unicast
Hello Experts,
Can someone explain me the difference between address-family ipv6 and address-family ipv6 labeled unicast. Per my understanding, i think both of them are used to send labelled IPv6 prefix advertisements through BGP..If so, are the following configs same?
address-family ipv6
neighbor 192.168.0.1 activate
neighbor 192.168.0.1 send-label
router bgp 10
neighbor 192.168.0.1
address-family ipv6 labelled unicast
Please let me know if my understanding is correct
Thanks
MukundhThanks for the reply Nagendra...
I have another related query regarding this. We have BGP neighborship flapping between 2 routers ...One is Cisco 7204 and another is Juniper M120 I think.... The Juniper logs show that BGP is flapped due to family inet6 not configured on the Juniper end and Juniper is receiving BGP advertisements with native IPv6 as next hop from Cisco when it shouldn't be receiving that.. The following are commands on Cisco and Juniper...

By the cisco command above, shouldn't cisco be sending only labelled ipv6 prefixes or am I wrong in this. And if Cisco sends both unlabelled and labelled prefixes, is there a way to make it send only ipv6 prefixes?
Thanks

Conditional Route Advertisement - VRF Address Family?
I would like to do conditional route advertisement within an IPv4 vrf address family but the "neighbor x advertise-map" command is not available within the vrf address family (at least in the code version I have). It is available in non-vrf address families.
Command/Config reference guides do not show any limitations regarding the command. Before I upgrade code (which may not be possible with my current platform) I wanted to see if anyone is doing this or if there is another way to accomplish the same task.
Thanks

Address family not supported by protocol family: bind
Over the past few days a number of users have reported connection issues with our application. We've been able to track the problem to this line of code:
ServerSocketChannel sc = ServerSocketChannel.open();
sc.socket().bind(new InetSocketAddress("localhost", 0)); <- error thrown
The following error is thrown:
java.net.SocketException: Address family not supported by protocol family: bind
sun.nio.ch.Net.bind(Native Method)
sun.nio.ch.ServerSocketChannelImpl.bind(Unknown Source)
sun.nio.ch.ServerSocketAdaptor.bind(Unknown Source)
sun.nio.ch.ServerSocketAdaptor.bind(Unknown Source)
I've read this is something to do with an IPv4 / IPv6 issue. But what I don't understand is that our users have had this working fine for months and we've never had any problems in the past, but within the last couple of days 10 people have contacted us, all with the same issue. We've not released any patches so we've not introduced the problem. Does anyone know what might have changed in the past few days? Did Microsoft release a patch to modify the IPv 4 / 6 protocols?
Apparently the issue might be resolved in Java7, but we have thousands of users, and rolling out a new version of Java is a big upheaval.
Any ideas???
BBBIt uses a JRE that is isolated for our application, so Java updates 'shouldn't' affect it. I have a sneaking suspicion that a Vista update may have changed something, but I can't be sure.
I'm working through the problem with one of our users, and I've changed the code from:
ServerSocketChannel sc = ServerSocketChannel.open();
sc.socket().bind(new InetSocketAddress("localhost", 0));To
ServerSocket sc = new ServerSocket();
sc.bind(new InetSocketAddress("localhost", 0));This works and I'm able to get an available port. However, later in the code it runs this section of code to connect the socket:
void connect() throws IOException, InterruptedException {
int retry;
for (retry = 0; retry < MAX_RETRY; retry++) {
try {
channel = SocketChannel.open();
channel.configureBlocking(false);
//connect to server
channel.connect(serverAddr);
//register events to listen
channel.register(selector, SelectionKey.OP_CONNECT);
while (!channel.isConnected()) {
if (selector.select(1) > 0) {
Set readyKeys = selector.selectedKeys();
Iterator i = readyKeys.iterator();
while (i.hasNext()) {
SelectionKey key = (SelectionKey) i.next();
i.remove();
SocketChannel keyChannel = (SocketChannel) key
.channel();
if (key.isConnectable()) {
if (keyChannel.isConnectionPending()) {
keyChannel.finishConnect();
break;
break;
} catch (Exception e) {
channel.close();
channel = null;
try {
Thread.sleep(150);
} catch (Exception ex) {
if (retry == MAX_RETRY) {
throw new InterruptedException("Maximum retry number reached!");
channel.register(selector, SelectionKey.OP_READ);
}It's now falling over on this line:
channel.connect(serverAddr);
java.net.SocketException: Address family not supported by protocol family: connect
serverAddr is a InetSocketAddress, channel is a SocketChannel, which appears not to be supported on the machine that are having these connection issues.
I'll be honest, I have little or no experience of implementing Sockets, and since I can't replicate the actual problem that our users are having it makes it even hard to fix it or try to code a workaround. The code above is from an OpenSource project, i.e. it's not something I wrote. In other words, I'm kinda up the 'proverbial creek'!
Could anybody be kind enough to steer me in the right direction for a workaround that doesn't use a SocketChannel? It really would be appreciated!

Difference between SAF service-family & address-family
Hello, I cant seem to find a simple definition of the difference between SAF service-family & address-family.
Could someone please explain these two terms.
Thanks kindly.In addition to the above ...
Rollup Patch (RUP): An aggregation of patches that may be at the functional level, or at a specific product/family release level. For example, a Flexfields rollup patch contains all the latest patches related to Flexfields at the time the patch was created. A Marketing Family 11.5.10 rollup patch contains all the latest Marketing patches released since, and applicable to 11.5.10
Family Pack: An aggregation of patches at the product family level. Family product codes always end in "_PF" and family packs are given alphabetical sequence such as 11i.HR_PF.B, 11i.HR_PF.C, and 11i.HR_PF.D. Family packs are cumulative. In other words, Discrete Manufacturing Family Pack G (11i.DMF_PF.G) contains everything in 11i.DMF_PF.F, which contains everything in 11i.DMF_PF.E, and so on.
If you search the rollup patch thru Metalink, it would tell you whether it is included in any other patchset (i.e. Family Pack) or not. -

Hi,
I am trying to reduce the routing table to our PE's which are currently 3750ME's. The 3750ME's only come with 128MB of DRAM so I am keen to reduce the size of the routing table amongst other things. Is there an equivalent to the aggregate-address ipv4 address family (within bgp) command for vpnv4 routes? Essentially I would like to filter, summarise or add default routes facing the PE's where possible. Being able to perform this level of granularity per vrf instance would be ideal.
I had read somewhere that vpn4 automatically summarises between P's and PE's but I wasn't 100% confident on the source of this information.there's no auto summarization, in fact your P routers shouldn't be running BGP and they shouldn't see any VPNv4 prefixes. There's no aggregate-address command under "address-family vpnv4", you put it under "address-family ipv4 vrf x". In other words, you summarize routes coming in from CE's in a VRF. Use "summary-only" keyword. It will result only in a summary vpnv4 route sent to other PE's

I need an advice in full connectivity between IPV4-IPV6 network
Hi ,
i have a network topology as attached.
as you see it has both ipv4 & ipv6
i just need an ideas here about how let all pcs (ipv4 & ipv6) to talk together based on the topology attached.Hello Ahmed,
You can use BGP with address-family ipv4 to provide routing for ipv4 and address-family ipv6 for ipv6.
This means between your router's you will have 2 BGP peerings, one for v4 one for v6.
If you use the ipv4 address for bgp address-family ipv6, you will have to apply a route-map on neighbor to change the next hop address to the relevant ipv6 interface address.

Advertising ipv4 routes via ipv6 bgp peers
Hello,
I have established IPV6 bgp sessions with ipv6 prefix-list filter. But ipv4 routes were advertised over this bgp session. Do I I need special configuration under address family or ipv4 prefix-list filters required ?
Note : the config was IBGP between 7200 routers and 6509 core switches.
Thank you all
NaelHi Nael,
This is because address-family ipv4 unicast gets activated by default when you configure a new neighbor in BGP. You either need to configure "no bgp default ipv4-unicast" or go under address-family ipv4 unicast and do a "no neighbor" for the ipv6 neighbor.
Hope this helps -
InterAS MPLS Option C (BGP IPv4 + Labels) IOS XR with eBGP multihop session
Hello,
Right now we have InterAS MPLS Option C configured between 2 autonomous systems.
Now we need to add more bandwith and would like to add another interface between the two routers establishing a multihop session using loopbacks to load share traffic.
I know that IOS-XR does not automatically learn directly connected host routes so for the XR router to assign labels you'll need to configure a static host route to ensure MPLS forwarding to the neighboring AS.
This works with directly connected neighbors but when I try to enable the multihop session, the XR does not assign labels even configuring the staic host route.
Does anybody has a configuration like that working?
Thanks!!
Jose.Hello Jose
There are basically two options in Option C L3VPN setup. I will discuss the first option for Multihop.
Following are the key points that distinguish the InterAS Option C from previous options.
1) External Multihop BGP address families are invoked between two different autonomous systems; however, these eBGP sessions are invoked between the route reflectors in each AS and not on the ASBR. The route reflector in each AS thus passes labeled ipv4 unicast VPN routes to the other AS. Note:- The route reflector in this case will have PE clients in the vpnv4 address family within that Autonomous System.
2) ASBRs facilitate the creation of InterAS LSP by providing labeled /32s for PE and Route Reflector loopback.
3) This option enhances scalability because ASBRs do not handle VPNv4 routes in fact this option gets rid of the extra L3VPN LFIB that is created as a result of option B . The LFIB size is minimal as we control the redistribution to the only 2 needed loopback addresses (remote ASBR and remote RR)
Sample config of the RR:
router bgp 102
address-family ipv4 unicast
address-family vpnv4 unicast
neighbor-group ibgp
remote-as 102
update-source Loopback0
address-family ipv4 unicast
route-reflector-client
address-family vpnv4 unicast
route-reflector-client
neighbor 192.168.253.3
remote-as 101
ebgp-multihop 255
description eBGP-RR-PEER-AS101
update-source Loopback0
address-family vpnv4 unicast
route-policy allow-all in
route-policy allow-all out
next-hop-unchanged
neighbor 192.168.254.1
use neighbor-group ibgp
neighbor 192.168.254.3
use neighbor-group ibgp
neighbor 192.168.254.4
use neighbor-group ibgp
On the PE router, the config will look something like this:
router bgp 102
address-family ipv4 unicast
redistribute ospf 1 metric 3333 route-policy interAS-optionc-out
allocate-label route-policy interAS-optionc-out
neighbor 65.10.20.1

Just for your clarification, 192.168.253.0/24 is the Remote AS networks and 192.168.254.0/24 is the local AS networks.
Hope this clarifies your doubts.

BGP Multi-instance was supposed to be released in XR 4.2, I could not find any mention of it in the Release notes for 4.2, 4.3, & 5.1?
How do I find out if it was implemented and if so how to configure it, if not if it is still on the road map?
Thanks,
JohnHello,
It is in release note XR .4.2:
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.2/general/release/notes/reln_a9k_42.html
And some writing on Cisco doc:
http://www.cisco.com/en/US/docs/routers/crs/software/crs_r4.2/routing/configuration/guide/b_routing_cg42crs_chapter_01.html#concept_E6B1D3D6B8CA4742AED837B3A94E826F
Below is the example what i did in my lab running 4.2.3:
