Hello Team,
So i intend to bring up a peering session with one of the providers who intends to send me over 120,000 Prefixes. Since am not very sure if my routers will handle such a big table, i want to configure the BGP maximum prefix so that i only "install/accept a few prefixes from this peer."
What's not clear about this configuration (seen on cisco documentation) is, if i configure "warning only" so that the peer is not dropped, will the excess prefixes be dropped or will be still be accepted but with warning messages?
Please advise.

Hello
Waring Only will NOT tear down the peering and the excess prefixes should still be advertised

Thank you Paul, so does that mean there is no way to filter out/limit the number of prefixes that should be learned from a peer?

You can filter that's not a problem, You could even filter prefixes before they are advertised to you but either ways you would need to know some information on what you want to filer (ip address /range, AS path/hop count, Med , regular expression etc..) prior to doing so.

Hi Paul,
For sure, yes, i would need to know some info prior to filtering, for some reason i thought there could be away to filter or limit the number of prefixes.
Thanks.
