4-12 MPLS Module Installation and User Guide
Configuring the Label Distribution Protocol
The following commands enable IP forwarding on the configured VLANs. The MTU
size is increased on the MPLS VLANs to accommodate the MPLS shim header:
enable ipforwarding vlan vlan1
config ip-mtu 1550 vlan vlan1
enable ipforwarding vlan vlan2
config ip-mtu 1550 vlan vlan2
enable ipforwarding vlan unc
The following command enables MPLS on VLANs vlan1 and vlan2:
config mpls add vlan vlan1
config mpls add vlan vlan2
The following command globally enables MPLS on the switch:
enable mpls
The following commands add vlan1 and vlan2 to the backbone area, each with a cost of
10. The 0.0.0.0 (backbone) area does not need to be created because it exists by default:
config ospf add vlan vlan2 area 0.0.0.0
config ospf vlan vlan2 cost 10
config ospf add vlan vlan1 area 0.0.0.0
config ospf vlan vlan1 cost 10
The following command enables distribution of local (direct) interfaces into the OSPF
area:
enable ospf export direct cost 10 ase-type-1
The following commands configure the OSPF router ID on the switch and enable the
distribution of a route for the OSPF router ID in the router LSA. Originating the router
ID as a host route allows other routers in the same OSPF area to establish indirect LSPs
for external routes to this router:
config ospf routerid 11.0.1.11
enable ospf originate-router-id
The following command enables OSPF:
enable ospf
