Command to debug
- #show bgp neighbor a.b.c.d rejected-routes
- #show ip bgp neighbor a.b.c.d received-routes
  - Display the routes received from the neighbor
- #show ip bgp neighbor a.b.c.d routes
  - Display the routes sent by the neighbor and accepted by the inbound BGP filters

Send output to tftp server.

       show ip bgp neighbor a.b.c.d received-routes | redirect tftp://x.x.x.x/received.txt 
       show ip bgp neighbor a.b.c.d routes | redirect tftp://x.x.x.x/routes.txt

To simplify testing use, soft reconfig (Check it doubles memory usage)

       neighbor a.b.c.d soft-reconfiguration in 
       clear ip bgp a.b.c.d soft in
