Static IPv6 route configuration
5
A metric is a value that the Layer 3 switch uses when comparing this route to other static routes in
the IPv6 static route table that have the same destination. The metric applies only to routes that
the Layer 3 switch has already placed in the IPv6 static route table.
The administrative distance is a value that the Layer 3 switch uses to compare this route with
routes from other route sources that have the same destination. (The Layer 3 switch performs this
comparison before placing a route in the IPv6 route table.) This parameter does not apply to routes
that are already in the IPv6 route table. In general, a low administrative distance indicates a
preferred route. By default, static routes take precedence over routes learned by routing protocols.
If you want a dynamic route to be chosen over a static route, you can configure the static route with
a higher administrative distance than the dynamic route.
TABLE 24 Static IPv6 route parameters
Parameter Configuration details Status
The IPv6 prefix and prefix length
of the route’s destination
network.
You must specify the
<dest-ipv6-prefix> parameter in
hexadecimal using 16-bit values
between colons as documented in
RFC 2373.
You must specify the <prefix-length>
parameter as a decimal value. A
slash mark (/) must follow the
<ipv6-prefix> parameter and precede
the <prefix-length> parameter.
Mandatory for all static IPv6 routes.
The route’s next-hop gateway,
which can be one of the following:
• The IPv6 address of a
next-hop gateway.
• A tunnel interface.
You can specify the next-hop gateway
as one of the following types of IPv6
addresses:
• A global address.
• A link-local address.
If you specify a global address, you do
not need to specify any additional
parameters for the next-hop gateway.
If you specify a link-local address, you
must also specify the interface
through which to access the address.
You can specify one of the following
interfaces:
• An Ethernet interface.
• A tunnel interface.
• A virtual interface (VE).
If you specify an Ethernet interface,
also specify the port number
associated with the interface. If you
specify a VE or tunnel interface, also
specify the VE or tunnel number.
You can also specify the next-hop
gateway as a tunnel interface. If you
specify a tunnel interface, also
specify the tunnel number.
Mandatory for all static IPv6 routes.
The route’s metric. You can specify a value from 1 – 16. Optional for all static IPv6 routes. (The
default metric is 1.)
The route’s administrative
distance.
You must specify the distance
keyword and any numerical value.
Optional for all static IPv6 routes. (The
default administrative distance is 1.)
