Defining Configured Explicit Paths

You can create explicit routing paths manually by configuring an explicit path with a name and a series of addresses (hops) from ingress to egress.

To manually configure explicit routing:

1. Define an explicit path and access Explicit Path Configuration mode.

   host1(config)#mpls explicit-path name xyz

   host1(config-expl-path)#

2. Do one of the following to configure the hops in the LSP:
   • Set the next hop (if need be) at a particular index in the explicit path.

     host1(config-expl-path)#index 5 next-address 172.18.100.5

   • Add the next hop (if need be) after a particular index in the explicit path.

     host1(config-expl-path)#append-after 5 next-address 192.168.47.22

3. Configure a next hpo at the end of the MPLS explicit path.

   host1(config-expl-path)#next-address 10.10.9.2

4. Enable the explicit path.

   host1(config)#mpls explicit-path name xyz

   Note: To prevent a partially configured explicit path from being used, do not enable it until you have finished configuring or modifying the path.

5. (Optional) List the currently configured explicit path.

   host1(config-expl-path)#list 5
