This example shows how to set up a virtual link to connect the backbone through area 1 for the
OSPFv3 topology that consists of areas 0 and 1 and virtual links 10.0.0.217 and 10.0.0.212:
router ospfv3 1
router-id 10.0.0.217
area 0
interface TenGigE 0/2/0/1
area 1
virtual-link 10.0.0.212
interface TenGigE 0/2/0/0
router ospfv3 1
router-id 10.0.0.212
area 0
interface TenGigE 0/3/0/1
area 1
virtual-link 10.0.0.217
interface TenGigE 0/2/0/0
In this example, all interfaces on router ABR1 use MD5 authentication:
router ospf ABR1
router-id 10.10.10.10
authentication message-digest
message-digest-key 100 md5 0 cisco
area 0
interface TenGigE 0/2/0/1
interface TenGigE 0/3/0/0
area 1
interface TenGigE 0/2/0/0
virtual-link 10.10.5.5
!
!
In this example, only area 1 interfaces on router ABR3 use MD5 authentication:
router ospf ABR2
router-id 10.10.5.5
area 0
area 1
authentication message-digest
message-digest-key 100 md5 0 cisco
interface TenGigE 0/9/0/1
virtual-link 10.10.10.10
area 3
interface Loopback 0
interface TenGigE 0/9/0/0

Summarize Subnetwork LSAs on OSPF ABR
If you configured two or more subnetworks when you assigned your IP addresses to your interfaces, you
might want the software to summarize (aggregate) into a single LSA all of the subnetworks that the local area
