Which command is used to define both exit interface and next hop in an IPv6 static route configuration?

The correct command to define both the exit interface and next hop in an IPv6 static route configuration uses the format where the exit interface is specified first, followed by the next hop. This is consistent with the syntax expectations for configuring static routes in IPv6 on Cisco devices.

In this command format, you begin with the ipv6 route command, followed by the destination address and prefix length, then indicate the exit interface that will be used to forward packets towards the next hop, and finally specify the next-hop address. This allows the router to understand not only where to send the packets but also through which interface these packets should exit.

The other options deviate from this correct format. Some may incorrectly place the next-hop before the exit interface, which does not align with the required syntax in Cisco's command-line interface for setting up IPv6 routes. Correctly structuring the command ensures the router processes the routing information accurately, leading to successful packet forwarding based on the defined static routes.
