We've introduced the recursive opaque value type for the MLDP forwarding equivalence class (FEC) element. The recursive opaque value helps to form Multipoint LDP (MLDP) point-to-multipoint (P2MP) tunnels between two autonomous systems (ASs), where the intermediate nodes do not have the route to reach the root node. To enable the recursive opaque value, configure the fec statement at the [edit protocols ldp p2mp recursive] hierarchy level.
