, Switch A, Switch B, Switch C, and Switch D reside in the same IS-IS routing
domain. Run IS-IS among them.
Switch A, Switch B, and Switch C belong to Area 10, and Switch D belongs to Area 20.
Configure neighbor relationship authentication between neighbors. Configure area authentication in
Area 10 to prevent untrusted routes from entering into the area. Configure routing domain authentication
on Switch C and Switch D to prevent untrusted routes from entering the routing domain.
