You are configuring all your devices for IPv6. Which of the following is the only device that requires the ipv6
unicast-routing command?

A.
Layer 2 switch

B.
Router

C.
Adaptive security appliance

D.
Wireless AP

Explanation:
Only the router requires the ipv6 unicast-routing command. The command ipv6 unicast-routing enables the
routing of IPv6 packets on a router. It is not required when you are simply configuring interfaces on devices that
participate in IPv6.
A Layer 2 switch can have an IPv6 address applied to its management interface and to any VLAN interfaces.
However, because the switch does no routing, it does not require the ipv6 unicast-routing command.
An adaptive security appliance (ASA) can also have IPv6 addresses applied to its interfaces and can route both
IPv6 and IPv4 traffic. However, it does not require the ipv6 unicast-routing command.
A wireless access point differs from a wireless router in that it operates as a switch or hub and does no routing.
Therefore, it does not require this command.Objective:
