[ no ] isis tag tagValue
Command introduced before JunosE Release 7.1.0.
Sets a route tag value for the IP addresses on an IS-IS interface before the route is propagated to other routers in an IS-IS domain. To use the route tag, you must reference it in a route map to set values and/or redistribute routes. The no version removes the route tag from the interface.
