send-metric-style
Configures the router to advertise narrow, wide or both metric styles when sending IS-IS link state packets.
Syntax: send-metric-style [narrow | wide | both]
narrow
Send only the original IS-IS narrow metric style. Narrow metrics range from 0 to 63 (6 bits).
wide
Send the traffic engineering wide metric style. Wide metrics range from 0 to 17777215 (24 bits).
both
Send both metric styles.
Description: IS-IS LSPs consist of a fixed header and a number of tuples commonly known as TLVs. The traditional IS-reachability TLV contains information about IS neighbors, including one octet devoted to information about the default metric. Only 6 bits of this octet are used to store the actual metric, which limits the value of the metric to a range from 0 to 63. Traffic engineering extensions expand this limitation from the traditional 6 bits to 24 bits.
Use the send-metric-style narrow command to advertise links using the traditional narrow (6 bits) metric style.
Use the send-metric-style wide command to advertise links using the traffic engineering wide (24 bits) metric style.
Use the send-metric-style both command to advertise both the narrow and wide metric styles.
Factory Default: Narrow.
Command Mode: Router configuration.
Example: In the following example,
- The send-metric-style wide command configures the router to advertise IS-IS links using the wide metric style.
- The show running-config isis command displays the setting:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#router isis net1
router(config-router)#send-metric-style wide
router(config-router)#end
router#show run isis
