LDP LSP configuration example

Network requirements
Switch A, Switch B, and Switch C all support MPLS.
Configure LDP to establish LSPs between Switch A and Switch C, so subnets 1 1.1.1.0/24 and 21.1.1.0/24
can reach each other over MPLS.
Configure LDP to establish LSPs only for destinations 1.1.1.9/32, 2.2.2.9/32, 3.3.3.9/32, 1 1.1.1.0/24,
and 21.1.1.0/24 on Switch A, Switch B, and Switch C.

Requirements analysis
To ensure that the LSRs establish LSPs automatically, enable LDP on each LSR.
•
To establish LDP LSPs, configure a routing protocol to ensure IP connectivity between the LSRs. This
•
example uses OSPF.
To control the number of LSPs, configure an LSP generation policy on each LSR.
•
Configuration procedure
1. Configure IP addresses and masks for interfaces, including the loopback interfaces, as shown
in Figure
2. Configure OSPF on each switch to ensure IP connectivity between them:
