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 a n d 21.1.1. 0 / 24
can reach each other over MPLS.
Configure LDP to establish LSPs for only 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.

Configuration considerations
LDP assigns labels according to routing information. To establish LDP LSPs, you must configure a routing
protocol to make sure the LSRs can reach each other. This example uses OSPF.
Enable LDP on each LSR.
To control the number of LSPs, configure an LSP generation policy on each LSR.
