IPv4 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 IPv4 LSPs automatically, enable IPv4 LDP on each LSR.
•
To establish IPv4 LDP LSPs, configure an IPv4 routing protocol to ensure IP connectivity
between the LSRs. This example uses OSPF.
•
To control the number of IPv4 LSPs, configure an IPv4 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:
