Configuring IPv6 Route Table Entries and Route Preferences

Beginning in Privileged EXEC mode, use the following commands to

configure IPv6 Static Routes.

Command Purpose
configure Enter global configuration mode.

Configure a static route.Use the keyword null instead of
the next hop router IP address to configure a static reject
route.
•
prefix/prefix-length
—The IPv6 network prefix and
prefix length that is the destination of the static route.
Use the ::/0 form (unspecified address and zero length
prefix) to specify a default route.
•
interface-type interface-number
—Must be specified
when using a link-local address as the next hop. The
interface-type can be
vlan
or
tunnel
.
•

next-hop-address

—The IPv6 address of the next hop
that can be used to reach the specified network. A link-
local next hop address must have a prefix length of 128.
The next hop address cannot be an unspecified address
(all zeros), a multicast address, or a loopback address. If
a link local next hop address is specified, the interface
(VLAN or tunnel), must also be specified.
•
preference
—Also known as Administrative Distance, a
metric the router uses to compare this route with routes
from other route sources that have the same network
prefix. (Range: 1-255). Lower values have precedence
over higher values. The default preference for static
routes is 1. Routes with a preference of 255 are
considered as “disabled” and will not be used for
forwarding. Routes with a preference metric of 254 are
used by the local router but will never be advertised to
other neighboring routers.
