How does a recursive static route function in IPv6?

A recursive static route in IPv6 functions by specifying the destination address and the next-hop address. In this context, the key aspect of a recursive static route is that it does not include an exit interface, which differentiates it from other types of static routes that may explicitly specify how to reach a network.

When a static route is defined with just the next-hop address, the router relies on its routing table to find out how to reach that next hop. This process is called "recursion" because the router may have to look up the next-hop address in its routing table to find its exit interface and thus reach the final destination.

In IPv6, routes can be quite straightforward since they prioritize the next-hop address to guide packet forwarding decisions. This helps streamline routing by minimizing the amount of stationary configuration on interfaces, making it easier for routers to determine paths dynamically based on the routing information they already hold.

The other options reflect different configurations or misconceptions about static routes in IPv6, but the essence of a recursive static route is its reliance solely on the next-hop address to function effectively.
