Configuring the Adjacency Check Feature

When enabled, the adjacency check feature permits an adjacency between two IS-IS interfaces only when both are configured for the same IP address type (IPv4 or IPv6) and are configured for the same subnet.

To enable the adjacency check feature, use the following command:
enable isis area area_name adjacency-check {ipv4 | ipv6}
To disable the adjacency check feature, use the following command:
disable isis area area_name adjacency-check {ipv4| ipv6}
