Usage Guidelines

IS-IS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

device(config-isis-router)# address-family ipv4 unicast
device(config-router-isis-ipv4u)# distance 40

The following example sets an administrative distance of 60 for the IPv6 unicast address family.

device# configure terminal
device(config)# router isis
device(config-isis-router)# address-family ipv6 unicast
device(config-router-isis-ipv6u)# distance 60
