mpls te
Enables/disables global traffic engineering.
Syntax: [no] mpls te {isis[level-1 | level-2] | ospf}
isis
Enables traffic engineering extensions for the IS-IS routing protocol.
level-1
Traffic engineering extensions are included in only level-1 LSAs.
level-2
Traffic engineering extensions are included in only level-2 LSAs.
ospf
Enables traffic engineering extensions for the OSPF routing protocol.
Description: MPLS traffic engineering uses an IGP to flood MPLS information to the entire network.
When traffic engineering is enabled, the IGP uses protocol extensions to distribute information about network resources. When you enable traffic engineering, the IGP adds traffic engineering link attributes to its LSAs.
Use the mpls te isis command to enable traffic engineering over IS-IS advertised interfaces.
Use the level-1 option to use IS-IS level-1 LSAs to build the traffic engineering database.
Use the level-2 option to use IS-IS level-2 LSAs to build the traffic engineering database.
Use the mpls te ospf command use OSPF LSAs to build the traffic engineering database.
You can enable traffic engineering for either IS-IS or OSPF, but not both. If you want to change the IGP, you must explicitly disable the currently running IGP before enabling another.
Use the no mpls traffic-engineering command to disable traffic engineering for the specified routing protocol and remove all configuration associated with MPLS, including tunnel defaults, tunnel parameter set and tunnel.
Factory Default: Disabled.
Command Mode: Configuration.
Example 1: In the following example:
- The mpls te isis level-1 command selects IS-IS as the IGP for traffic engineering and specifies that the traffic engineering database will be built using Level 1 IS-IS LSAs.
- The show mpls te command displays the new setting:
router(config)#mpls te isis level-1
router(config-te)#end
router#show mpls te
Traffic engineering is enabled
IGP: isis level-1
.
.
.
Example 2: In the following example, the mpls te ospf command selects OSPF as the IGP for traffic engineering:
router(config)#mpls te ospf
Example 3: In the following example:
- The no mpls te ospf command disables traffic engineering using OSPF.
- The mpls te isis level-1 command selects IS-IS as the IGP for traffic engineering
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#no mpls te ospf
router(config-te)#end
router(config)#mpls te isis level-1
