Default Values

By default, no static routes are added to the IPv6 route table. If a static route is created, the administrative
distance is 1 by default.

Functional Notes
Each static route is only added to the IPv6 route table when the IPv6 interface is configured and in an UP
state. There are three types of static routes that can be used: directly attached, recursive, and fully
specified.
A directly attached static route is a route in which the next hop for the route is entered as an interface.
Packets destined for the specified network are assumed to be directly reachable on the specified interface.
If you are using a directly attached static route, and the interface you are using uses Layer 2 addresses (for
example, as an Ethernet interface does), then address resolution is performed when a packet is delivered
to the network. For Point-to-Point Protocol (PPP) interfaces, the packet is simply forwarded through the
interface in the same way that a packet is forwarded when an IPv6 on-link prefix is defined at the interface.
A recursive static route is a route in which the next hop for the route is entered as the IPv6 address of the
next-hop router. When a recursive static route is used, AOS attempts to determine the interface used to
reach the next-hop address. Recursive routes are added to the route table only when the router has
determined which interface to use for egress traffic.
A fully specified static route is a route in which the next hop is entered as an IPv6 address and an interface
for the next-hop router is specified. This type of static route restricts the use of the route to the specified
interface. A fully specified static route MUST be used when the next hop is specified by its link-local
address, which alone has no context of location.
Usage Examples
The following example creates a static route in the IPv6 routing table that has a local-link next-hop
address, egresses from the ethernet 0/1 interface, includes a tag of 3, and has an administrative distance
of 2:
(config)#ipv6 route 2001:DB8:3F::/48 fe80::202:b3ff:fe1e:8345 ethernet 0/1 tag 3 2
60000CRG0-35E
Optional. Specifies that traffic is routed to the null interface. The router
drops all packets destined for the null interface. Use the null interface to
allow the router to advertise a route, but not forward traffic to the route.
Optional. Specifies an administrative distance associated with the static
route, and is used to determine the best route when multiple routes to the
same destination exist. The route with the lowest administrative distance is
the preferred route. Administrative distance range is 1 to 255.
Optional. Specifies a number to use as a tag for this route. Valid range is 1
to 65535.

Command was expanded to include the tunnel interface.
