BGP IDLE

[aw75635]

Hello.

I am trying to create a simple set up for BGP.

R1 to R2 will use remote as 3

R2 to R3 will use rmeote as 89

Things look fine between R1 and R2.

But between R2 and R3 i get these messages - see attached file.

Why does it behave like this?

It should work fine, as I see.

Best regards!

Look at the document and try the option as suggested :

https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/116189-problemsolution-technology-00.html

if still not working, post complete router configuration look and advise here.

Hello.

Thank you for your replay.

I have tried it, but it does not seems to help.

I have even reinstalled R3.

If I use BGP remote-as 3 on R3, then it does speak with R2. But if I use another remote-as, it does not work.

Attached you may find the configuration of the routers.

Best regards.

is this test Lab?

do you have reachability between R2 and R3-  is the right interface connected each other

can you post-show CDP neigh from both R2 and R3

ping also from both the routers ? from R2: ping 192.168.103.1023from R3: 192.168.103.102

Hello.

This is a lab. yes, the routers can ping each other, R1 to R2 and R2 to R3.

I can ssh from R1 to R2 and from R2 to R3.

Best regards!

This is normal behavior. The remote-as you configure on the neighbor statement for R2 on R3 needs to match the AS number configured on R2, which is 3.
