Again thanks to everyone for your prompt reply. I couldn't make it work . I
configured soft reconfig inbound on both sides but on BB3 it always give
same error.. . My lab time is fisnished so could not debug it further , may
be will do it tomorrow.if time permits
I still can't understand R5 is showing 7 routes have been advertised to BB3
using sh ip bgp neighbour x.x.x.x advertise-routes and BB3 doesn't recieve
those routes, recd prefix is 0 where these routes are gone ???? I have never
seen one side say advertise and other side didn't recive it in BGP after
all BGP uses TCP so called reliable transport mechanism.
Any thoughts ???
