partial-path-list
Defines/deletes a traffic engineering partial path list.
Syntax: [no] partial-path-list name
name
Specifies the name of a pre-existing path list.
Description: Multiple paths often times have a number of nodes in common from the ingress to some midpoint before splitting off on a different path to the egress. The partial-path-list command provides for the configuring of such a partial path that will be used by more than one LSP with different egress nodes.
The partial-path-list command does not create a partial path. It assigns partial path status to an already existing path list within a given tunnel configuration mode context. The context can be tunnel default, tunnel parameters, or tunnel name. A partial path is first created as a standard strict or loose path using the path-list command. Within the tunnel default, tunnel parameters, or tunnel name command mode, the partial-path-list command to specifies this already existing path list as a partial path within the current command mode context.
Use the partial-path-list command in tunnel default, tunnel parameters, or tunnel name command mode to designate a pre-existing path list as a partial path in the current tunnel context.
Use the no partial-path-list command to delete the partial path from the current tunnel context. Deleting the partial path has no affect on the original path list.
Use the show mpls te tunnel lsp command to display LSP partial path status.
Factory Default: None.
Command Mode: traffic engineering tunnel-default, tunnel-parameters, or tunnel-name.
Example: In the following example:
- The mpls te isis command enables MPLS using the IS-IS IGP.
- The path-list name command defines a path-list named test1 and enters path-list configuration mode.
- The next address commands define 2 hops in the path list.
- Entering tunnel name command mode for the test1 tunnel, 192.20.20.20 is configured as the egress for the tunnel.
- Using the partial-path-list command, the test1 path list is configured as a partial path leading to the egress:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#mpls te isis
router(config-te)#path-list test1
router(config-te-path-list)#next-address 201.12.15.15 loose
Path hop number: 1
router(config-te-path-list)#next-address 201.6.14.18 loose
Path hop number: 2
router(config-te-path-list)#exit
router(config-te)#tunnel test1
router(config-te-tunnel)#egress 192.20.20.20
router(config-te-tunnel)#partial-path-list test1
router(config-te-tunnel)#end
router#show mpls te tunnel lsp test1
