We are setting up a new router setup. We have the folowing BGP configuration:
#show ip bgp config
Current BGP configuration:
capability as4 enable
neighbor 188.8.131.52 remote-as 39637
neighbor 184.108.40.206 remote-as 201290
address-family ipv4 unicast
address-family ipv4 multicast
address-family ipv6 unicast
address-family ipv6 multicast
The problem is that the network 220.127.116.11/22 is not advertised to neighbor 18.104.22.168
The BGP sesion is established and i recive routes from that BGP neighbor.
We running on a CER 2024 whit firmware 5.5

Does the route exist in the local IP table? Does that router own that subnet?
you might also look into the redisribute if it's a static, directly connected or ospf route

Create a prefix-list with the ip address in there.
ip prefix-list netblocks seq 10 permit 22.214.171.124/22
ip prefix-list netblocks seq 1000 deny 0.0.0.0/0
Create a route-map matching on the prefix list
route-map netblocks-outbound permit 20
match ip address prefix-list netblocks
bind route-map for the neighbor to announce the ip space.
neighbor 126.96.36.199 route-map out netblocks-outbound
neighbor 188.8.131.52 route-map out netblocks-outbound
clear bgp neighbor for configuration changes to take effect.
You do need a null for that route if it's not in the CER already.
ip route 184.108.40.206/22 null0 dist 250
