Command Syntax

Supplemental
Information
It is essentially a route to nowhere. Null routes are used too prevent packets from being routed to the default route in the event of a
hardware or routing failure.
Note: Null routes should have a less desirable admin distance than the actual destination, therefore they should be used only if the
actual destination is not available due to a hardware or routing failure.
To remove the static route, use the no option.
Parameters
<ipv6-address>
Destination route address.
<prefix-length>
A decimal value that indicates the length of the IPv6 prefix
<int>
Integer number, usually zero.
[admin-distance
<int>]
Provides static routes priority over other types of routes except for connected routes. The default admin-distance is 1.
[metric <int>]
Compares this route to other routes with the same admin distance.
