[j-nsp] improving global unicast convergence (with or without BGP-PIC)

[Alexander Arseniev]

Hello,

JUNOS is different from IOS - BGP session will stay up until holdtime 
fires but the protocol NH will disappear, the routes will be 
recalculated and network will reconverge even if BGP session to gone 
peer is still up.

I tested it many times.

Actually, if You configure "local-address", the behaviour is different - 
JUNOS declares the IP from gone interface is not available and tears 
down the session.

HTH

thx

Alex
