  1. hi

    will I need to advertise the internal routing network into BGP
    for example internal EIGRP is using subnet 126.89.120.64/26

  2. Thank you Rene.

    Getting back to Alfred0's question regarding null routes, why would someone need to advertise a prefix which is not existing in their local AS? Yes, it does make sense to use null route(s) with route summarization. I think there is one more case where you need null route, namely when you don't want your public (peering) IP to be advertised upstream in BGP.

  3. Hi,

    How do I advertise public IP to a peer? for example, my server 10.123.10.50 should NAT to <public-IP> and routed to neighbor.

    The router only knows the 10.123.10.0/24 network as connected.

    Best.

  5. HI Rene,
    SInce BGP only advertises network which matches in the routing table, why doesn't it advertise prefixes learnt from other neighbor as its own network to other neighbors .
    the show ip route command does show route is being self-originated but the last update still shows that is prefix is being learnt from neighbor
    Please advise
