The restart-time advertised in the graceful-restart capability sent to
members of this peer-group. This is the estimated time (in seconds) it
will take for the BGP session to be re-established after a restart. This
can be used to speed up routing convergence by the peer in case that this
BGP speaker does not come back after a restart. This value (if configured)
overrides the global value configured in juniBgpGracefulRestartRestartTime.
