I am studying for the CCNP and I am setting up a simple BGP connection between two routers but can't get it to work.

Here are the configs.


Router A

int lo0

ip add

int fa0/0

ip add

router bgp 1

neighbor remote-as 2

Router B

int lo0

ip add

int fa0/0

ip add

router bgp 2

neighbor remote-as 1

Any reason why this isn't connecting? Physical layer is good as I can ping connected interfaces from both sides.



I have this problem too.

Hello Richard,

a useful command is

sh ip bgp summary

as you have just discovered is possible to build a BGP session without advertising nothing.

in this case you see 0 as the number of prefixes received.

If you use sh ip route bgp you don't see nothing but the BGP session is up.

Think of BGP session as a communication channel between two devices

Hope to help
