MPLS configuration examples
Configuring static LSPs
Network requirements
•
Switch A, Switch B, and Switch C support MPLS.
•
Establish static LSPs between Switch A and Switch C so that subnets 10.1.1.0/24 and 21.1.1.0/24
can access each other over MPLS.
•
Check the connectivity of the static LSPs.

Configuration considerations
•
On an LSP, the out label of an upstream LSR must be identical with the in label of its downstream
LSR.
•
Configure an LSP for each direction on the forwarding path.
•
Configure a static route to the destination address of the LSP on each ingress node. Such a route is
not required on the transit and egress nodes. You do not need to configure any routing protocol on
the switches.
Configuration procedure
1.
Configure the IP addresses of the interfaces.
Configure the IP addresses and masks of the interfaces according to
. (Details not shown)
2.
Configure a static route to the FEC destination address on each ingress node.
# Configure a static route to network 21.1.1.0/24 on Switch A.
[SwitchA] ip route-static 21.1.1.0 24 10.1.1.2
# Configure a static route to network 11.1.1.0/24 on Switch C.
[SwitchC] ip route-static 11.1.1.0 255.255.255.0 20.1.1.1
3.
Enable MPLS.
# Configure MPLS on Switch A.
