Configures the metric value for an interface under IPv6 Intermediate System-to-Intermediate System (IS-IS) MT.
The default is 10.
Interface subtype configuration mode
IS-IS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.
Each IS-IS interface has a separate metric value. In IPv6 IS-IS MT, different metrics are configured on an interface for IPv4 and IPv6. When the metric value is configured for an interface, it rebuilds the route LSP and triggers IPv6 IS-IS MT SPF calculation.
The no form of the command resets the metric value to the default value of 10.
The following example changes the metric value for Level 1 packets for an Ethernet interface under IPv6 IS-IS MT to 25.
device# configure terminal device(config)# interface ethernet 1/1 device(conf-if-eth-1/1)# isis ipv6 metric level-1 25
The following example changes the metric value for Level 2 packets for a loopback interface under IPv6 IS-IS MT to 60.
device# configure terminal device(config)# interface loopback 1 device(config-Loopback-1)# isis ipv6 metric level-2 60
