Configuring IPv6

Configuring Static Routing for IPv6

Before configuring a static IPv6 route, you must enable routing by using the ip routing global
configuration command, enable the forwarding of IPv6 packets by using the ipv6 unicast-routing global
configuration command, and enable IPv6 on at least one Layer 3 interface by configuring an IPv6
address on the interface.
Beginning in privileged EXEC mode, follow these steps to configure an IPv6 static route:
Command
Step 1 configure terminal
Step 2 ipv6 route ipv6-prefix/prefix length
{ipv6-address | interface-id [ipv6-address]}
[administrative distance]
Step 3 end

Purpose
Enter global configuration mode.
Configure a static IPv6 route.
ipv6-prefix—The IPv6 network that is the destination of the
•
static route. It can also be a hostname when static host routes are
configured.
/prefix length—The length of the IPv6 prefix. A decimal value
•
that shows how many of the high-order contiguous bits of the
address comprise the prefix (the network portion of the address).
A slash mark must precede the decimal value.
ipv6-address—The IPv6 address of the next hop that can be used
•
to reach the specified network. The IPv6 address of the next hop
need not be directly connected; recursion is done to find the
IPv6 address of the directly connected next hop. The address
must be in the form documented in RFC 2373, specified in
hexadecimal using 16-bit values between colons.
interface-id—Specify direct static routes from point-to-point
•
and broadcast interfaces. With point-to-point interfaces, there is
no need to specify the IPv6 address of the next hop. With
broadcast interfaces, you should always specify the IPv6
address of the next hop, or ensure that the specified prefix is
assigned to the link, specifying a link-local address as the next
hop. You can optionally specify the IPv6 address of the next hop
to which packets are sent.
You must specify an interface-id when using a link-local
Note
address as the next hop (the link-local next hop must also be
an adjacent router).
administrative distance—(Optional) An administrative distance.
•
The range is 1 to 254; the default value is 1, which gives static
routes precedence over any other type of route except connected
routes. To configure a floating static route, use an administrative
distance greater than that of the dynamic routing protocol.
Return to privileged EXEC mode.
