The configuration is missing the address-family ipv4 unicast and address-familyipv6 unicast commands under router isis 1.

IPv6 unicast routing has not been enabled globally on the Cisco IOS XE router.

The gi0/0/0 and gi0/0/1 interfaces are not participating in the router isis 1 routing instance.

Multitopology IS-IS must beenabled to support both IPv4 and IPv6.
