IP Connectivity

Question Image

Refer to the exhibit. For internet connectivity, a public IPv6 address must be configured. Which command should be configured on the R2 WAN interface connected to the service provider?

  • A ipv6 address fe80::/10
  • B ipv6 address 2001:db8:433:37:7710:ffff:ffff:ffff/64 anycast
  • C ipv6 address 2001:db8:123:45::4/64
  • D ipv6 address fe80::260:3EFF:FE11:6770 link-local
Explanation

A WAN interface facing the ISP needs a globally routable IPv6 address to reach the internet, which must be a global unicast address rather than a link-local or anycast address. Addresses in the fe80::/10 range are link-local only and never leave the local segment, and the anycast option is not a standard host address assignment for this interface, leaving 2001:db8:123:45::4/64 as the valid global unicast configuration.
