Configuring L2 Tunnels MPLS Configuration
R2 is a transit LSR with interfaces to R1 and R3. The following is the configuration for R2:
mpls set path to_rs5_primary ip-addr 220.1.1.2 type strict hop 3
! Configure tunnel LSP to R3 with explicit path p1
mpls create label-switched-path to_rs3_rsvp to 111.1.1.3 no-cspf preference 10
mpls set label-switched-path to_rs3_rsvp primary p1 no-cspf retry-interval 5 mtu 1000
! Configure tunnel LSP to R5
mpls create label-switched-path to_rs5_rsvp to 111.1.1.5 no-cspf
mpls create policy dip_to_rs5 dst-ipaddr-mask 152.1.0.0/16
mpls set label-switched-path to_rs5_rsvp policy dip_to_rs5
mpls set label-switched-path to_rs5_rsvp primary to_rs5_primary no-cspf retry-interval 5
