Configuring an intra-domain multi-segment PW
Network requirements
As shown in Figure 72 , there is no public tunnel between PE 1 and PE 2, and there is an MPLS TE tunnel
between PE 1 and P, and an MPLS TE tunnel between P and PE 2. Configure a multi-segment PW
between PE 1 and PE 2, so CE 1 and CE 2 can communicate over the backbone. The multi-segment PW
includes an LDP PW between PE 1 and P, and a static PW between P and PE 2. The two PWs are
connected on P.
