JunOS supports a 'local-address' statement within a neighbor or BGP 
group, which is pretty much the same as update-source on cisco, although 
it uses an IP rather than interface name.

It's my understanding that Junos has no equivalent to the Cisco 'update-source loobback0'. I haven't run into to problems peering with the respective loopback between a Cisco to Juniper but have with a Juniper to Juniper (that is attempting to bring the peers up via the loopbacks). Although my tests were limited and lack too many details, I'm curious if anyone has run up against this issue and what your recommendations are.
