    hi chenoi,

     

     What I understand from the output below is that:

     

     1. your neighbor is advertising you 286836 prefixes via BGP.

     2. you have an import policy that only installs 15 prefixes out of them.

     

     This command won't show you the path and other information. You may want to try one of the following:

     


    show route protocol bgp

    show route protocol bgp terse | match \* #===> to see only the 'best' ones.

     

    Cheers,

    Erdem.

     

    P.S: I take it that your bgp advertisement problem in some other thread is solved by now? 🙂

    Hi Chenoi

     

    I think this could be perfectly normal. It all depends on how many routes you are actually receiving from this neighbor.

     

    Your inet.0 table shows that you have 15 Active routes and  286821 inactive routes. This are not necessary from the neighbor 65.25.1.6.

     

    If the hidden routes are from  65.25.1.6, than use the "hidden" command to show the routes.

     

    show route receive-protocol bgp 65.25.1.6 hidden

     You can also check how many routes you expect to receive per neibhor with the summary command

     

    lab@riga> show bgp summary Groups: 1 Peers: 1 Down peers: 0 Table Tot Paths Act Paths Suppressed History Damp State Pending inet.0 10 10 0 0 0 0 Peer AS InPkt OutPkt OutQ Flaps Last Up/Dwn State|#Active/Received/Damped... 10.0.0.7 65000 284 282 0 0 2:06:25 10/10/0 0/0/0 lab@riga> show route receive-protocol bgp 10.0.0.7 table inet.0

    inet.0: 53 destinations, 63 routes (53 active, 0 holddown, 0 hidden)
    Restart Complete
    Prefix Nexthop MED Lclpref AS path
    * 10.0.7.1/32 10.0.0.7 100 I
    * 10.0.7.2/32 10.0.0.7 100 I
    * 10.0.7.3/32 10.0.0.7 100 I
    * 10.0.7.4/32 10.0.0.7 100 I
    * 10.0.7.5/32 10.0.0.7 100 I
    * 10.0.7.6/32 10.0.0.7 100 I
    * 10.0.7.7/32 10.0.0.7 100 I
    * 10.0.7.8/32 10.0.0.7 100 I
    * 10.0.7.9/32 10.0.0.7 100 I
    * 10.0.7.10/32 10.0.0.7 100 I

     Notice in the output above, that I have 53 active routes but only 10 learned via 10.0.0.7
