next address
Defines/deletes the next-address hops in the path list.
Syntax: next-address ip-address [strict | loose]
ip-address
IP address of the LSR that is the next hop in the path list.
strict
Indicates that this hop in the path consists of exactly the specified LSR. The specified LSR must be adjacent.
loose
Indicates that this hop in the path may insert additional LSRs as required.
Description: A traffic engineering path list consists of all or a sub-set of the LSRs that an LSP traverses between this (ingress) router and the egress router. A path list may include only one LSR (the egress LSR) or as many as 256 LSRs.
You configure path-lists on a hop-by-hop basis. Each hop is configured as either strict or loose. If a hop is strict, the LSP uses only the specified LSR to reach the next hop. Strict hops must be to directly connected (adjacent) routers.
If the hop is loose, the LSP may insert additional hops as required. Loose hops can be to LSRs that are not directly connected to the previous hop.
Use the next-address ip-address strict command to define a next hop where the LSP traverses only the specified adjacent LSR.
Use the next-address ip-address loose command to define a next hop where additional hops may be inserted into the LSP. The specified LSR is not required to be adjacent.
Factory Default: Strict.
Command Mode: Traffic engineering path-list.
Example: In the following example:
- The path-list command defines a path list named ToPVE.
- The next-address ip-address commands define four hops in the path-list.
- The show mpls te path-list command displays the new path list:
router(config)#mpls te ospf
router(config-te)#path-list SFOtoDC
router(config-te-path-list)#next-address 12.1.1.2
Path hop number: 1
router(config-te-path-list)#next-address 16.5.1.121
Path hop number: 2
router(config-te-path-list)#next-address 16.5.2.68
Path hop number: 3
router(config-te-path-list)#exit
router(config-te)#exit
router(config)#end
router#show mpls te path-list SFOtoDC
path-list SFOtoDC
next-address 12.1.1.2
next-address 16.5.1.121
next-address 16.5.2.68
