Assigning IPv6 Addresses on an Interface
To assign IPv6 addresses to an interface, use the following commands.
1. Assign an IPv6 address to the interface.
CONF-INT-type slot/port mode
ipv6 address ipv6 address
IPv6 addresses are normally written as eight groups of four hexadecimal digits; separate each group by a colon (:).
The format is A:B:C::F/128.
2. Bring up the interface.
CONF-INT-type slot/port mode
no shutdown
Assigning Area ID on an Interface
To assign the OSPFv3 process to an interface, use the following command.
The ipv6 ospf area command enables OSPFv3 on an interface and places the interface in the specified area. Additionally,
the command creates the OSPFv3 process with ID on the router. OSPFv2 requires two commands to accomplish the same
tasks — the router ospf command to create the OSPF process, then the network area command to enable OSPFv2 on
an interface.
NOTE: The OSPFv2 network area command enables OSPFv2 on multiple interfaces with the single command. Use the
OSPFv3 ipv6 ospf area command on each interface that runs OSPFv3.
● Assign the OSPFv3 process and an OSPFv3 area to this interface.
CONF-INT-type slot/port mode
ipv6 ospf process-id area area-id
○ process-id: the process ID number assigned.
○ area-id: the area ID for this interface.
Assigning OSPFv3 Process ID and Router ID Globally
To assign, disable, or reset OSPFv3 globally, use the following commands.
● Enable the OSPFv3 process globally and enter OSPFv3 mode.
CONFIGURATION mode
ipv6 router ospf {process ID}
The range is from 0 to 65535.
● Assign the router ID for this OSPFv3 process.
CONF-IPV6-ROUTER-OSPF mode
router-id {number}
○ number: the IPv4 address.
The format is A.B.C.D.
NOTE: Enter the router-id for an OSPFv3 router as an IPv4 IP address.
● Disable OSPF.
CONFIGURATION mode
no ipv6 router ospf process-id
● Reset the OSPFv3 process.
EXEC Privilege mode
clear ipv6 ospf process
