Configuring LDP to establish LSPs dynamically
Network requirements
Switch A, Switch B, and Switch C support MPLS.
Configure LDP to establish LSPs between Switch A and Switch C so that subnets 11.1.1. 0 / 24 a n d
21.1.1.0/24 can reach each other over MPLS. Test the connectivity of the LSPs.
Figure 25 Network diagram
Configuration considerations
• Enable LDP on the LSRs. LDP dynamically distributes labels and establishes LSPs and thus there is no
need to manually configure labels for LSPs.
• LDP uses routing information for label distribution. You must configure a routing protocol to learn
routing information. OSPF is used in this example.
Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF to ensure IP connectivity between the switches:
# Configure OSPF on Switch A.
