Route precedence is as follows:

• Host route to the destination.
• Route for a prefix of the destination. If there are routes to multiple prefixes of the destination, the route with the most specific prefix is chosen.
• Default route.

For IPv4, the concept exists of a special default multicast route with a destination of 224.0.0.0 and a netmask of 255.255.255.255. For IPv6, there is no special default multicast route. Because all IPv6 multicast addresses start with FF, the following prefix route serves the same function as the default multicast route:

destination = FF00::/8
