Deploying Cisco Service Provider Edge Technologies (SPEDGE, legacy) — Question 5

When is it appropriate to activate the VPNv6 address family?

Answer options

• A. when implementing 6PE
• B. when running dual stack at the provider edge
• C. when implementing 6to4 tunneling D.

Correct answer: C

Explanation

The correct answer is C because the VPNv6 address family is specifically used to facilitate 6to4 tunneling, which allows IPv6 packets to be transmitted over an IPv4 network. The other options, while related to IPv6 implementation, do not directly pertain to the activation of the VPNv6 address family.
