Configuring the MPLS Family on Core Interfaces
Because LDP is used as the signaling protocol to
transport MPLS labels across the core of the network, you must include
the family mpls statement at the [edit interfaces interface-name unit logical-unit-number] hierarchy level. Include the statement on all router interfaces
in the path from the local PE router to the remote PE router across
the core network that transports the Layer 2 circuit traffic.
[edit]
interfaces {
interface-name {
unit logical-unit-number {
family inet {
address ip-address/prefix;
}
family mpls;
}
}
}
