However, my issue is the CRS1 router is not advertising out to my ebgp peer even though the ip address is active.

Can I know why?

Hello Siew,

228.1.1.0/30 is not an IPv4 unicast address but it is a multicast address

203.1.1.1/32 has to be present in the local BGP table in order to be advertised to the eBGP peer

Hope to help

Giuseppe
