I have two routers like bellow:
in the Router1, I configured like bellow:
! router bgp 100 bgp log-neighbor-changes no synchronization neighbor 188.8.131.52 remote-as 200 network 184.108.40.206 mask 255.255.255.0 network 220.127.116.11 mask 255.255.255.0 !
and the Router2 have bellow configure:
! router bgp 200 bgp log-neighbor-changes no synchronization !
I only executed the Router1's interface gig0/0:
neighbor 18.104.22.168 remote-as 200
I did not execute the neighbor command in Router2.
Whether there need the neighbor command in Router2 interface to Router1?
you see, in the Router1 bgp 100 I added:
network 22.214.171.124 mask 255.255.255.0 network 126.96.36.199 mask 255.255.255.0
but in the Router2 bgp 200 there do not have the routes.
