Configuring L2 Tunnels MPLS Configuration
Two LSPs are configured on R3: one is from R3 to R5, while the other is from R3 to R1 and restricted to traffic destined
for the 124.2.0.0.16 subnet. The following is the configuration for R3:
! Create VLANs and interfaces
vlan create ldp_if1 id 120
vlan create ip_ldp port-based id 175
vlan create to_rs1_only ip id 50
vlan add ports gi.12.2 to ip_ldp
vlan add ports gi.12.1 to ldp_if1
vlan add ports gi.15.1 to to_rs1_only
interface create ip to_rs2 address-netmask 210.1.1.2/16 vlan ip_ldp
interface create ip to_rs4 address-netmask 110.1.1.1/16 vlan ldp_if1
interface add ip lo0 address-netmask 111.1.1.3/32
! Configure OSPF
ip-router global set router-id 111.1.1.3
ospf create area backbone
ospf add stub-host 111.1.1.3 to-area backbone cost 5
ospf add interface to_rs2 to-area backbone
ospf add interface to_rs4 to-area backbone
ospf start
! Configure MPLS
mpls add interface to_rs2
mpls add interface to_rs4
mpls create label-switched-path to_rs1_rsvp to 111.1.1.1 no-cspf
mpls create label-switched-path to_rs5_rsvp to 111.1.1.5 no-cspf
mpls create policy dip_to_rs1 dst-ipaddr-mask 124.2.0.0/16
mpls set label-switched-path to_rs1_rsvp policy dip_to_rs1
mpls start
! Configure RSVP
rsvp add interface to_rs2
rsvp add interface to_rs4
rsvp start
! Configure LDP
ldp add interface lo0
ldp map ports gi.15.1 customer-id 20
maps port gi.15.1 to customer-id 20
ldp add l2-fec customer-id 20 vlan 50 to-peer 111.1.1.1
sends label mapping for customer-id 20/VLAN
50 to R1
ldp add remote-peer 111.1.1.1
adds R1 as LDP peer
ldp start
