[ no ] tunnel mpls [ traffic-eng ] autoroute announce [ ospf | isis ]
Command introduced before JUNOSe Release 7.1.0.
Configures the LSP tunnel to register its endpoint (the egress router) with the configured routing protocol so that the protocol can use the tunnel to determine routes. If you do not specify a routing protocol, the default is both IS-IS and OSPF. The no version disables endpoint announcements.
