Configuring IPv6 Host Functions
•
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
OL-8915-03
Floating static routes—Any of the three types of static routes can be floating static routes, used to
back up dynamic routes learned through configured routing protocols. A floating static route is
configured with a less efficient administrative distance than the routing protocol it is backing up.
Therefore, the dynamic route is always used for routing traffic in preference to the floating static
route. If the dynamic route is lost, the floating static route is used in its place.
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.
Note
You must specify an interface-id when using a link-local
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.
