Hi Paul ,
You are right , "clear ip bgp * soft in" can be used with or without
soft reconfiguration, my mistake.
And yes when the soft reconfiguration is off, a route refresh request is
send , and when is soft reconfiguration on, the routes are processed
from stored unmodified peer updates.
Thx
Dan
