BGP MultiHop

If your using loopback to source BGP sessions in a single direction, do you
have to specify "neighbor/ebgp-multihop " on both bgp peers? Or do you have
to use the "neighbor\ebgp-multihop" command on both peer involved in the peer
relationship?

For example:
(assuming that IGPs or statics are in place and life is good)

(Lo1-1.1.1)--R1-------------R2

R1 neighbors statements:

neighbor 4.4.4.4 remote-as (100)

R2 neighbor statements

neighbor 1.1.1.1 remote-as 200
neighbor 1.1.1.1 update-source-loopback Lo0
neighbor 1.1.1.1 ebgp-multihop 255

I suspect that you only need to use the "neighbor/ebgp-multihop" statement on
the bgp peer peering with a host using an ip address on a non-connected
network.

Thanks,
