Configured loopback interfaces with ipv4 and ipv6 address on ASR 9k1 Need to advertise to iBGP neighbor. Used combination of prefix set and route policy but not working.

Configured loopback interfaces with ipv4 and ipv6 address on ASR 9001. Need to advertise to iBGP neighbor. Used combination of prefix set and route policy but not working.
Any idea how can we do this..

!

This is the config.. I studied there is no need of route - policy for route propagation via iBGP . My agenda is to advertise these Loopback prefixes via BGP to iBGP neighbor. I can't use IGP:

!

interface Loopback3
ipv4 address 172.16.1.1 255.255.255.0
ipv6 address 2002:1234:c019::1/64
!
interface Loopback4
ipv4 address 172.16.2.1 255.255.255.0
ipv6 address 3002:1234:c019::1/64
!
prefix-set abc
172.16.1.0/24,
172.16.2.0/24
end-set
!
prefix-set xyz
2002:1234:c019::/64,
3002:1234:c019::/64
end-set
!
neighbor 31.55.142.59
remote-as xxxx
timers 10 30
password encrypted 011215015E06021935181D5B48
address-family ipv4 unicast
route-policy abc out
!
neighbor 2a00:2380:300c:1000::29
remote-as xxxx
timers 10 30

Hello,

is this a partial configuration ? Just in case it is not, you need to activate the neighbors and announce the networks:

neighbor 31.55.142.59
remote-as xxxx
timers 10 30
password encrypted 011215015E06021935181D5B48
address-family ipv4 unicast

neighbor 31.55.142.59 activate
network 172.16.1.0/24
network 172.16.2.0/24
route-policy abc out
!
neighbor 2a00:2380:300c:1000::29
remote-as xxxx
timers 10 30
password encrypted 0207175E0E0B0B37581A5A4B54
address-family ipv6 unicast

neighbor 2a00:2380:300c:1000::29 activate
network 2002:1234:c019::/64
network 3002:1234:c019::/64
route-policy xyz out

Its not woking. ASR 9k1 does not give the privilege to activate the neighbor under AF and hence, advertise the networks using network command

Hello,

what user group are you in ? Make sure you are in the right user group and have the right task ID's assigned.

Post the full config of your router...which user ID are ypu logged in with ?

I agree it seems like you don’t even have a BGP neighbor.  Did you verify that? Show ip BGP summary.

[aseem]

Yes, BGP for both ipv6 and ipv6 is Up and even the routes are being received from the neighbor.

The only concern is unable to advertise the routes from ASR 9k1 to ibgp neighbor

[Georg Pauwen]

Hello,

do you have the iBGP neighbors configured with next-hop-self ? Can you post the full configs of both iBGP neighbors ?
