Configuring Static Lsps - HP 12500 Series Configuration Manual

NOTE:
By default, Ethernet interfaces, VLAN interfaces, and aggregate interfaces are in DOWN state. To
configure such an interface, first use the undo shutdown command to bring the interface up.

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
Configure IP addresses for the interfaces according to
1.
Configure a static route to the destination address of the FEC on each ingress node.

# Configure a static route to network 21.1.1.0/24 on Switch A.
<SwitchA> system-view
[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> system-view
[SwitchC] ip route-static 11.1.1.0 255.255.255.0 20.1.1.1
Enable MPLS.
