Different route types in the IPv6 routing table
Default route (::/0): A static route used by all traffic that has a destination network not reachable through any other IPv6 route in the routing table. See Configuring the IPv6 default route.
Directly connected routes: Destinations on the router itself. One route is automatically entered per configured IPv6 interface. Each such route is automatically assigned an administrative distance of "0" and a metric of "1". Directly connected routes include:
VLAN interface: Where the routing switch is connected to a next-hop router on the same interface, a route is automatically entered for the network on which the VLAN is configured. This includes destinations for both global unicast and link-local addresses configured on the routing switch for that VLAN.
Manually configured IPv6 loopback interfaces: IPv6 loopback interfaces that are manually configured.
Loopback route: A static IPv6 route automatically created in the routing table for use if other routes to a destination are not available. The gateway is a loopback interface (lo0) and the destination is ::1/128.
Statically configured routes: On a given routing switch, one static route can be configured directly into the routing table for each destination. In the default configuration, administrative distance and route metric are both "1". See Configuring static IPv6 routes.
