+FEC nexthop entry resolution over MPLS networks
+-----------------------------------------------
+
+The LSP associated with a BGP labeled route is normally restricted to
+directly-connected nexthops. If connected nexthops are not available,
+the LSP entry will not be installed. This command permits the use of
+recursive resolution for LSPs, similar to that available for IP routes.
