I have BGP peering with carrier. I would like to only accept routes from the carrier that I am interested in.
My Router : 128.100.1.1
router bgp 64514
no synchronization
bgp log-neighbor-changes
neighbor 10.10.10.2 remote-as 64514
neighbor 10.10.10.2 next-hop-self

I am learning routes of 128.100.8.0 and 128.100.9.0 and 128.100.10.0. I would like to try and block 128.100.8.0 from coming to my router with Prefix List but doesn't work.
