BGP IPv6 Route Filtering on Cisco IOS

Lessons Discussion

Hello Rene,

Thank you for explanation!

I was trying to configure this on an existing lab setup but ran into an issue. It is slightly off the topic of discussion.

Can BGP not perform IPv6 in a vrf? I notice that this lesson does not show IPv6 within a vrf and when I try to perform it myself I receive the following error:

Hello Christopher

BGP does support IPv6 in a VRF. However, the specific error message you are getting is because the iptest VRF has not been enabled for IPv6. You must make sure that the following is configured under your iptest VRF definition:

R1(config)#vrf definition iptest
R1(config-vrf)#address-family ipv6
R1(config-vrf-af)#exit
R1(config-vrf)#exit
R1(config)#

Check it out and let us know if this was indeed the issue.

I hope this has been helpful!

Laz,

Thanks, as always. Turns out vrf definition is the new (multiprotocol) way forward. I guess I’ll start training myself to use that in all instances vice “ip vrf”.
