Configuring L2 Tunnels MPLS Configuration
R4 is a transit LSR with interfaces to R3 and R5. The following is the configuration for R4:
Two LSPs are configured on R5. The LSP from R5 to R1 is configured with a loose explicit path of 2 hops and is
restricted to traffic destined for the 124.2.0.0/16 subnet. The LSP from R5 to R3 is configured with a primary and
secondary path. The primary path is a strict explicit path of 3 hops (R5, R4, R3) and the secondary path is a strict
explicit path of 5 hops (R5, R6, R1, R2, R3). The following is the configuration for R5:
ldp add l2-fec customer-id 10 to-peer 111.1.1.5 send customer-id mapping to R5
