MPLS Configuration Configuring L2 Tunnels
Note If you configure more than one tunnel LSP to the same destination, you can
specify the preferred LSP to be used with the transport-lsp option of the ldp
set l2-fec command. You can also specify if an alternate LSP can be used. The
transport-lsp option of the ldp set l2-fec command allows you to assign
a specific LSP to specific customer traffic. This provides a way to offer different
LSP services to different customers.
The following is the configuration for R1:
! Configure VLANs and interfaces
vlan make trunk-port gi.4.1
vlan make trunk-port gi.4.2
vlan create cust1 port-based id 100
vlan create cust2 port-based id 200
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.4.2 to cust1
vlan add ports gi.4.1 to ldp_in
vlan add ports gi.6.1,gi.2.2,gi.4.1 to cust1
vlan add ports gi.3.1,gi.4.1 to cust2
interface create ip to_rs2 address-netmask 200.1.1.1/16 vlan ldp_in LDP-signaling VLAN to R2
interface create ip to_rs6 address-netmask 201.1.1.1/16 vlan ldp_in2 LDP-signaling VLAN to R6
interface create ip ip_32 address-netmask 124.2.1.1/16 port gi.3.2
interface add ip lo0 address-netmask 111.1.1.1/32
! Configure OSPF

ospf add interface to_rs2 to-area backbone
ospf add interface to_rs6 to-area backbone
ospf start
! Configure MPLS
mpls add interface to_rs2

! Configure explicit path p1 to R3
mpls create path p1 num-hops 2
mpls set path p1 ip-addr 200.1.1.1 type loose hop 1
mpls set path p1 ip-addr 210.1.1.2 type loose hop 2
! Configure explicit path to R5
mpls create path to_rs5_primary num-hops 3
mpls set path to_rs5_primary ip-addr 201.1.1.1 type strict hop 1
mpls set path to_rs5_primary ip-addr 201.1.1.2 type strict hop 2
