Normally an as path loop or other sanity check results in this state. >From the config below does not seem this is the case. Perhaps add keep-all, restart/soft clear session, and then display hidden. Perhaps something will jump out.
Does tracing show any errors when the routes are processed? Unreachable next hop normally is just hidden so does not seem the case here. Should not matter, but I normally doe not specify peer-as for an int group. Again should not break things but worth trying w/o.

And by missing, I don't mean 'inactive' or 'hidden'. I have four routers peering through a full-mesh IBGP, one of which is advertising several routes that were received from a route reflector client. The routes are being sent from the route reflector router to all IBGP sessions and they are seen by only three out of four of the non-client peers. This one particular "problem" router doesn't have the prefixes anywhere in its RIB. There are no import policies on IBGP sessions denying any prefixes. Routes received from route-reflector client: edge02# run show route receive-protocol bgp 192.168.205.51 inet.0: 280459 destinations, 1146831 routes (279785 active, 3 holddown, 1448 hidden) Restart Complete Prefix Nexthop MED Lclpref AS path * 172.16.234.0/25 192.168.205.54 0 100 I * 172.16.236.0/27 192.168.205.55 0 100 I * 172.16.236.32/28 192.168.205.55 0 100 I * 172.16.236.48/30 192.168.205.56 0 100 I * 172.16.236.144/28 192.168.205.55 0 100 I * 172.16.236.160/29 192.168.205.55 0 100 I * 172.16.237.128/25 192.168.205.56 0 100 I * 172.16.239.224/27 192.168.205.51 0 100 I 192.168.206.129 is sending these routes to 192.168.206.128, which is a non-client peer: edge02# run show route advertising-protocol bgp 192.168.206.128 172.16.236.0/22 inet.0: 280471 destinations, 1146944 routes (279808 active, 0 holddown, 1399 hidden) Restart Complete Prefix Nexthop MED Lclpref AS path * 172.16.236.0/27 192.168.205.55 0 100 I * 172.16.236.32/28 192.168.205.55 0 100 I * 172.16.236.48/30 192.168.205.56 0 100 I * 172.16.236.144/28 192.168.205.55 0 100 I * 172.16.236.160/29 192.168.205.55 0 100 I * 172.16.237.128/25 192.168.205.56 0 100 I * 172.16.239.224/27 192.168.205.51 0 100 I 192.168.206.128 doesn't show these routes anywhere: edge01> show route receive-protocol bgp 192.168.206.129 172.16.192.0/18 inet.0: 280324 destinations, 940059 routes (279811 active, 0 holddown, 1210 hidden) Restart Complete edge01> show route receive-protocol bgp 192.168.206.129 172.16.192.0/18 edge01> hidden inet.0: 280327 destinations, 940062 routes (279815 active, 0 holddown, 1210 hidden) Restart Complete And the view from the other two non-client peers: core02> show route receive-protocol bgp 192.168.206.129 172.16.192.0/18 core02> table inet.0 inet.0: 280139 destinations, 567582 routes (279540 active, 0 holddown, 770 hidden) Restart Complete Prefix Nexthop MED Lclpref AS path * 172.16.234.0/25 192.168.205.54 0 100 I * 172.16.236.0/27 192.168.205.55 0 100 I * 172.16.236.32/28 192.168.205.55 0 100 I * 172.16.236.48/30 192.168.205.56 0 100 I * 172.16.236.144/28 192.168.205.55 0 100 I * 172.16.237.128/25 192.168.205.56 0 100 I * 172.16.239.224/27 192.168.205.51 0 100 I core01> show route receive-protocol bgp 192.168.206.129 172.16.192.0/18 core01> table inet.0 inet.0: 280147 destinations, 567688 routes (279612 active, 0 holddown, 727 hidden) Restart Complete Prefix Nexthop MED Lclpref AS path * 172.16.234.0/25 192.168.205.54 0 100 I * 172.16.236.0/27 192.168.205.55 0 100 I * 172.16.236.32/28 192.168.205.55 0 100 I * 172.16.236.48/30 192.168.205.56 0 100 I * 172.16.236.144/28 192.168.205.55 0 100 I * 172.16.237.128/25 192.168.205.56 0 100 I * 172.16.239.224/27 192.168.205.51 0 100 I Thanks, evt _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
