Configuring MPLS Traffic Engineering for IS-IS
This task explains how to configure IS-IS for MPLS TE. This task is optional.
For a description of the MPLS TE tasks and commands that allow you to configure the router to support
tunnels, configure an MPLS tunnel that IS-IS can use, and troubleshoot MPLS TE, see Implementing
MPLS Traffic Engineering on Cisco IOS XR Software.
Prerequisite
Your network must support the MPLS Cisco IOS XR software feature before you enable MPLS TE for
IS-IS on your router.
Note You must enter the commands in the following task list on every IS-IS router in the traffic-engineered
portion of your network.
Restrictions
MPLS traffic engineering currently does not support routing and signaling of LSPs over unnumbered IP
links. Therefore, do not configure the feature over those links.
Step 5
hello-password keychain keychain-name [level {1
| 2}] [send-only]
Example:
RP/0/RP0/CPU0:router(config-isis-if)#
hello-password keychain isis_b
Configures the authentication password for an IS-IS
interface.
Step 6
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-isis-if)# end
or
RP/0/RP0/CPU0:router(config-isis-if)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
