  1. hi

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

  2. Can you shed any light on the default information originate and it's use in BGP.

  3. Hi Rouzbeh,
    1. If no mask is specified, default mask is used, that is /8 in your example.
    2. When Rene said "exact mask has to be added in network command" meant that if we have a prefix in routing table (say, and we want this prefix to be injected in bgp with network command we should use

    router bgp 1

    in our config.
    If we are going to use:

    router bgp 1

    , router will assume an implicit mask (
    So prefix will not enter bgp table because we do not have in routing table. We have but not
    Briefly, if we have in r. table, we should use EXACT prefix (of course) and mask (!) in network statement
    Hope it helps.

  4. Hlw Rene,

    Hope you are doing great ..

    One questions ..

    The BGP router will trigger a routing update to neighbor if belonging subnets are flap again & again in internal domain ?? How could we get routing upadate stability if BGP router always send Update. Could you please explain more on it .Many thanks


  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
