Ensure that OSPFv3 areas are assigned.
Note
All device interfaces must be assigned to one of the defined areas on an OSPFv3 device. When an interface is assigned to an area, all corresponding subnets on that interface are automatically included in the assignment.
-
Enter the
configure terminal command to access global configuration mode.
device# configure terminal
-
Enter the
interface command and specify an interface.
device(config)# interface ethernet 1/1
-
Enter the
ipv6 address command to add an IPv6 address to the interface.
device(conf-if-eth-1/1)# ipv6 address 2001:1:0::1:1/64
-
Enter the
ipv6 ospf area command.
device(conf-if-eth-1/1)# ipv6 ospf area 0
Area 0 is assigned to the specified interface with the IPv6 address of 2001:1:0:1::1/64.
-
Enter the
exit command to return to global configuration mode.
device(conf-if-eth-1/1)# exit
-
Enter the
interface command and specify an interface.
device(config)# interface ethernet 2/1
-
Enter the
ipv6 address command to add an IPv6 address to the interface.
device(conf-if-eth-2/1)# ipv6 address 2001:1:0::2:1/64
-
Enter the
ipv6 ospf area command.
device(conf-if-eth-2/1)# ipv6 ospf area 1
Area 1 is assigned to the specified interface with the IPv6 address of 2001:1:0:2::1/64.
The following example configures and enables OSPFv3 on two specified interfaces, and assigns an interface to two router areas.
device# configure terminal
device(config)# interface ethernet 1/1
device(conf-if-eth-1/1)# ipv6 address 2001:1:0::1:1/64
device(conf-if-eth-1/1)# ipv6 ospf area 0
device(conf-if-eth-1/1)# exit
device(config)# interface ethernet 2/1
device(conf-if-eth-2/1)# ipv6 address 2001:1:0::2:1/64
device(conf-if-eth-2/1)# ipv6 ospf area 1
