You may want to just configure system default-address-selection, which
makes outbound connection attempts default to using the loopback address
rather than the IP on the interface that the packet went out (like Cisco
does). This is usually "better" in all respects, and solves the IBGP
problem too (and without having to hard-code specific router IP
addresses in your IBGP groups).
