> we have Juniper M120 routers with single Routing Engine (RE) , and I want to enable the Graceful Restart (GR) feature for BGP OSPF MPLS protocols , but I found in some sources that it is usless to enable GR for a router with a single RE , and it can can only work as helper GR for Routers with redundant RE.
