[c-nsp] BGP routes disappearing

[Hank Nussbacher]

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
