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_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
