You are leading design discussions about IPv6 implementation into an existing Enterprise network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes…

The correct answer is A. If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD B. IPv6 is transparent on Layer 2 switches, so no changes are needed to the Layer 2 switches. For IPv6 multicast, switches must support MLD snooping to control multicast traffic efficiently. IPv6 itself is transparent to Layer 2 switching, so older switches can forward IPv6 frames without

Question

You are leading design discussions about IPv6 implementation into an existing Enterprise network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these switches for successful IPv6 implementation. Which two responses do you give? (Choose two.)

Options

  • AIf IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD
  • BIPv6 is transparent on Layer 2 switches, so no changes are needed to the Layer 2 switches.
  • CIf IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND
  • DIf IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6
  • EIf IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6
