I don't have the ccbootcamp labs but one requirement is as BGP works on tcp por
t 179, the network you're trying to establish connection with must be reachable
in the ip route table so a tcp connection can be established between the peers
.

I am doing ccbootcamp lab8 and ran across a problem that I solved but I am
not sure why the problem is there to begin with (although I have a feeling I
am missing something elementary).
When forming ibgp peering between two routers the adjacency is never formed
, debugging BGP gets me
>From R1:
BGP: 137.20.60.1 open active, local address 137.20.25.1
BGP: 137.20.60.1 open failed: Connection refused by remote host
>From R6:
2d02h: BGP: 200.200.200.1 went from Idle to Active
2d02h: BGP: 200.200.200.1 open active, delay 7272ms
2d02h: BGP: 200.200.200.1 open active, local address 137.20.64.6
2d02h: BGP: 200.200.200.1 open failed: Connection refused by remote host
R6 is an RR client of R1
after the change
R1:
BGP: 137.20.60.1 open active, local address 200.200.200.1
BGP: 137.20.60.1 went from Active to OpenSent
BGP: 137.20.60.1 sending OPEN, version 4
BGP: 137.20.60.1 OPEN rcvd, version 4
R6:
2d02h: BGP: 200.200.200.1 rcv message type 1, length (excl. header) 10
2d02h: BGP: 200.200.200.1 rcv OPEN, version 4
2d02h: BGP: 200.200.200.1 went from Connect to OpenSent
2d02h: BGP: 200.200.200.1 sending OPEN, version 4, my as: 2
2d02h: BGP: 200.200.200.1 rcv OPEN w/ OPTION parameter len: 0
2d02h: BGP: 200.200.200.1 went from OpenSent to OpenConfirm
changing the BGP update source on R1 to the loopback fixes everything, why
?
I did not see any reference to any requirement on the ip from which a BGP
speaker tries to form iBGP connections.
Any insight is welcome.
