Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 389

The network team is planning to implement IPv6 on the company's existing IPv4 network infrastructure. The network currently uses IS-IS to share routes between peers. Which task must the team perform so that IS-IS will run in multitopology mode on the updated IPv6 network?

Answer options

• A. Configure the links between the network routers as point-to-point.
• B. Configure the network routers to use metric-style wide.
• C. Configure the network routers as Level 2 routers.
• D. Configure the IS-IS IPv6 metric on the dual-stack links.

Correct answer: B

Explanation

The correct answer is B because configuring the routers to use metric-style wide is necessary for IS-IS to support multitopology routing. Options A and C do not address the requirement for multitopology in IS-IS, and option D is incorrect because simply configuring the IPv6 metric does not enable multitopology mode.
