I am getting an issue that is a router has so many entries in bgp table but bgp route is blank. Can anyone specify how it is possible and how to configure it, so that no routes from bgp in routing table. Below is the situation.

A>show ip protocols

*** IP Routing is NSF aware ***

 

Routing Protocol is "bgp 65535"

  Outgoing update filter list for all interfaces is 100

  Incoming update filter list for all interfaces is not set

  Mapping external information into routing table via 'BGP-IPV4-RIB-FILTER'

  Route flap dampening configured and enabled

  Halflife time 10 minutes, reuse value 1500

  Suppress value 2000, maximum suppress time 15

  IGP synchronization is disabled

  Automatic route summarization is disabled

  Neighbor(s):

    Address          FiltIn FiltOut DistIn DistOut Weight RouteMap

    x.x.x.x                              100        SET-NEXTHOP

    x.x.x.x                              100        SET-NEXTHOP

    x.x.x.x                              100        SET-NEXTHOP

    x.x.x.x                              100        SET-NEXTHOP

 

  Maximum path: 1

  Routing Information Sources:

    Gateway         Distance      Last Update

    x.x.x.x                         20      1y45w

    x.x.x.x                         20      1y45w

    x.x.x.x                         20      1y45w

    x.x.x.x                         20      1y45w

  Distance: external 20 internal 200 local 200

Hello,

Try to check "show ip bgp 1.0.4.0/24" and "show runn | sec bgp"
