D.

multi topology without enabling transition feature

Answers
Suggested answer: B

Explanation:

For single-topology IS-IS IPv6, routers must be configured to run the same set of address families. IS- IS performs consistency checks on hello packets and will reject hello packets that do not have the same set of configured address families. For example, a router running IS-IS for both IPv4 and IPv6 will not form an adjacency with a router running IS-IS for IPv4 or IPv6 only. In order to allow adjacency to be formed in mismatched address-families network, the adjacency-check command in IPv6 address family configuration mode must be disabled.
