The correct answer is B. IS-IS uses TLV structure to construct messages, making IS-IS more flexible and scalable C. In order to support IPv6, IS-IS needs to add a new TLV to carry IPv6 address information. D. For IS-IS, adding new features only requires adding a new TLV. See the full explanation below for the reasoning.
