It's from debug-
Jul 14 18:19:10: BGP: reset all neighbors due to User reset
Jul 14 18:19:10: BGP:A.B.C.202 went from Active to Idle
Jul 14 18:19:20: BGP: Import timer expired. Walking from 1 to 1
Jul 14 18:19:30: BGP: A.B.C.202 went from Idle to Active

Where i'm wrong?

DO you have an ACL applied to any of these interfaces ?

On rtrb you said update source E0/0. rtra should use that address for the neighbor statements like you did on rtrb.

ip route B.C.D.0 255.255.255.0 serial 0.1 permanent
