Nothing like solving your own issues.

I have a simple iBGP peer defined as follows:

 neighbor 128.139.197.146
  remote-as 378
  update-source Loopback0
  address-family ipv4 unicast


I have a GigE interface defined as:

interface GigabitEthernet0/0/0/43.1
 ipv4 address 192.0.2.1 255.255.255.0
 encapsulation dot1q 1

This iBGP peer feeds me /32s with nexthop set as 192.0.2.1/32. Problem is all routes disappear.

Neighbor        Spk    AS MsgRcvd MsgSent   TblVer  InQ OutQ Up/Down  St/PfxRcd 128.139.197.146   0   378   10437  627880 10060119    0    0 00:15:41          0


If the feed sets the IP to 192.0.2.2 then the BGP routes appear in the routing table.  If I then change the IP address on interface GigabitEthernet0/0/0/43.1 to 192.0.2.2 then the routes disappear as well after having made it into the routing table.


I am obviously missing something very simple.  Clue-bat welcome.


Thanks,

Hank
