OSPFv3 Virtual Link Configuration
 To display the OSPF Virtual Link Configuration page, click Routing > OSPFv3 > Advanced
> Virtual Link Configuration. The following page is displayed.
 Configure the OSPFv3 Virtual Link.
1. Enter the Area ID of the OSPF area.
An Area ID is a 32-bit integer in dotted decimal
format that uniquely identifies the area to which a router interface connects. Virtual links
may be configured between any pair of area border routers having interfaces to a
common (non-backbone) area.
2. Configure the Neighbor Router ID by entering the neighbor portion of a V
irtual Link
specification. Virtual links may be configured between any pair of area border routers having
interfaces to a common (non-backbone) area.
3. In the Hello Interval field, enter the OSPFv3 hello interval for the specified interface in
seconds.
This parameter must be the same for all routers attached to a network. Valid
values range from 1 to 65,535. The default is 10 seconds.
4. In the Dead Interval field, enter the OSPFv3 dead interval for the specified interface in
seconds.
This specifies how long a router will wait to see a neighbor router's Hello packets
before declaring that the router is down. This parameter must be the same for all routers
attached to a network. This value should a multiple of the Hello Interval (for example, 4).
Valid values range from 1 to 65,535. The default is 40.
5. In the Iftransit Delay Interval field, enter the OSPFv3
Transit Delay for the specified
interface. This specifies the estimated number of seconds it takes to transmit a link state
update packet over the selected interface. Valid values range from 1 to 3600 seconds (1
hour). The default value is 1 second.
6. In the Retransmit Interval field, enter the OSPFv3 retransmit interval for the specified
interface.
This is the number of seconds between link-state advertisements for adjacencies
belonging to this router interface. This value is also used when retransmitting database
descriptions and link-state request packets. Valid values range from 1 to 3600 seconds (1
hour). The default is 5 seconds.
Sequence The sequence number field is a signed 32-bit integer.
It is used to detect old and duplicate link state
advertisements. The larger the sequence number,
the more recent the advertisement.
Checksum
The checksum is used to detect data corruption of an
advertisement. This corruption can occur while an
advertisement is being flooded, or while it is being
held in a router's memory. This field is the checksum
of the complete contents of the advertisement,
except the LS age field.
