LDP configuration examples
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 11.1.1.0/24 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, 11.1.1.0/24,
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 17 . (Details not shown.)
2. Configure OSPF on each switch to ensure IP connectivity between them:
