MPLS Configuration Configuring L2 Tunnels
Two LSPs are configured on R1. The LSP from R1 to R5 is configured with a strict explicit path of 3 hops (R1, R6,
and R5) and is restricted to traffic destined for the 152.1.0.0/16 subnet. The LSP from R1 to R3 is configured with a
loose explicit path of 2 hops. The following is the configuration for R1:
! Configure VLANs and interfaces
vlan make trunk-port gi.2.1
customer ports must be trunk ports for 802.1q packets
vlan make trunk-port gi.6.2
customer ports must be trunk ports for 802.1q packets
vlan make trunk-port gi.5.1
customer ports must be trunk ports for 802.1q packets
vlan create ldp_in port-based id 110
vlan create ldp_in2 port-based id 120
vlan add ports gi.4.2 to ldp_in2
vlan add ports gi.4.1 to ldp_in
interface create ip to_rs2_1 address-netmask 200.1.1.1/16 vlan ldp_in
LDP-signaling VLAN interface
interface create ip to_rs2_second address-netmask 201.1.1.1/16 vlan ldp_in2
