Configuring the IPv6 default route

The IPv6 default route (::/0) is a static route used for all traffic that has a destination network not reachable through any other IPv6 route in the routing table. For more information on static routes, see IPv6 Static Routing.

Syntax

ipv6 route ::/0 <ipv6–gateway–addr> distance <1–255>

no ipv6 route ::/0 <ipv6–addr>

Used in the global config context to configure the default route and gateway to use for traffic sent to the default route.

::/0 : Specifies the default IPv6 route.

<ipv6–gateway–addr> : Specifies the next-hop router for traffic sent to the default route.

distance <1–255> : Specifies the administrative distance to associate with a static route. Default: 1; Range: 1–255.

The no form of the command deletes the default route for the specified next-hop destination from the routing table.

distance: Set the administrative distance to associate with this static route.
name: Configure the static route name.
tag: Specify the tag that can be used to filter redistribution of this route via route-maps

Configuring the IPv6 default route

If 2001:db8:c::9f:35 is the IPv6 address of your ISP router, all nonlocal traffic could be directed to the ISP by configuring the following default route:

Switch(config)# ipv6 route ::/0 2001:db8:c::9f:35

To view the default route in the routing table, use show ipv6 route.
