[j-nsp] Junos 9.3r3.8 BGP

[Truman Boyes]

Hi Ivan,

EBGP usually uses interface addresses on the same subnet between the  
peers. Of course you don't have to do it this way, but if you are  
sourcing from your loopback address you will need to make sure the  
peer knows how to reach your loopback, and you will need to enable  
multi-hop. (I see you have multihop enabled).

Also, do you have a route to reach your peer's loopback address?

Best,
Truman Boyes
