[j-nsp] receiving end of graceful-restart enabled by default?

[Gary Tate]

And to add the answer to the question.  The receive end router also 
needs to have graceful restart enabled because it needs to act as a 
helper.  This configuration is not automatic.  Just like any other 
capabilities exchange the receive router must tell the restarting 
router that it is restart capable, exchange timers (I'm assuming bgp 
peers) etc and this is only done if you configure graceful restart on 
that router also.
