Configuring IPv6
Beginning in privileged EXEC mode, follow these required and optional steps to configure IPv6 OSPF:
Command
Step 1
configure terminal
Step 2
ipv6 router ospf process-id
Step 3
area area-id range {ipv6-prefix/prefix length}
[advertise | not-advertise] [cost cost]
Step 4
maximum paths number-paths
Step 5
exit
Step 6
interface interface-id
Step 7
ipv6 ospf process-id area area-id [instance
instance-id]
Step 8
end
Step 9
show ipv6 ospf [process-id] [area-id] interface
[interface-id]
or
show ipv6 ospf [process-id] [area-id]
Step 10

Purpose
Enter global configuration mode.
Enable OSPF router configuration mode for the process. The
process ID is the number administratively assigned when
enabling the OSPF for IPv6 routing process. It is locally
assigned and can be a positive integer from 1 to 65535.
(Optional) Consolidate and summarize routes at an area
boundary.
area-id—Identifier of the area about which routes are to be
•
summarized. It can be specified as either a decimal value or
as an IPv6 prefix.
ipv6-prefix/prefix length—The destination IPv6 network
•
and 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.
advertise—(Optional) Set the address range status to
•
advertise and to generate a Type 3 summary link-state
advertisement (LSA).
not-advertise—(Optional) Set the address range status to
•
DoNotAdvertise. The Type 3 summary LSA is suppressed,
and component networks remain hidden from other
networks.
•
cost cost—(Optional) Metric or cost for this summary route,
which is used during OSPF SPF calculation to determine the
shortest paths to the destination. The value can be 0 to
16777215.
(Optional) Define the maximum number of equal-cost routes to
the same destination that IPv6 OSPF should enter in the routing
table. The range is from 1 to 64, and the default is 16.
Return to global configuration mode.
Enter interface configuration mode, and specify the Layer 3
interface to configure.
Enable OSPF for IPv6 on the interface.
instance instance-id—(Optional) Instance identifier.
Return to privileged EXEC mode.
Display information about OSPF interfaces.
Display general information about OSPF routing processes.
(Optional) Save your entries in the configuration file.
