Hi,
I have a Cisco ASR 1001-X with full-feed BGP from multiple upstreams and a /24 IP pool is advertised to them.
When a peer 1.2.3.61 advertises a /32 route over BGP example 1.2.3.15/32 with community as 65001:666, the
route-map
is unable to replace the community (even tried using additive) or remove it (tried using none). Even the other attributes like local-preference are not being set as mentioned in the
route-map
I even changed the
route-map
direction to out but still the same.
I want to set this community 7890:0 so I can advertise the /32 route to upstreams with this updated community.
Please help.
