IPv6 Configuration Guide K/KA/KB.15.15

Syntax:
[no] area area-id virtual-link router-id dead-interval 1 - 65535
In the ospf3 context, this command is used on both ABRs in a virtual link to change
the number of seconds that a neighbor router waits for a hello packet from the
specified interface before declaring the interface "down." This should be some
multiple of the Hello interval.
The dead-interval setting must be the same on both ABRs on a given virtual
link.
area-id
Specifies the OSPFv3 area in which both ABRs in a given virtual link operate.
In this use, the area ID is sometimes termed "transit area ID."
This value must be the same for both ABRs in the virtual link. If the area does
not exist, this command creates it.
router-id
For an ABR in a given virtual link, this is the router ID (in decimal or 32-bit dotted
decimal format) used to create the link on that ABR.
This value is the router ID of the opposite router in the virtual link. See the
description of router-id in the syntax description in the section “Configuring
a virtual link” (page 222).
The no version restores the default value.
Use show ipv6 ospf3 virtual-link router-id to view the current setting.
See the example at “Viewing OSPFv3 virtual link information” (page 243).
Default: 40 seconds
Adjusting a hello interval on a virtual link
Syntax:
area area-id virtual link router-id hello-interval 1 - 65535
In the ospf3 context, used on both ABRs in a virtual link to indicate the length of
time between the transmission of hello packets between the ABRs on opposite ends
of the virtual link. The hello-interval setting must be the same on both ABRs on a
given virtual link.
area-id
Specifies the OSPFv3 area in which both ABRs in a given virtual link operate.
In this use, the area ID is sometimes termed "transit area ID". This value must
be the same for both ABRs in the virtual link. If the area does not exist, this
command creates it.
router-id
For an ABR in a given virtual link, this is the router ID (in decimal or 32-bit dotted
decimal format) used to create the link on that ABR.
This value is the router ID of the opposite router in the virtual link. See the
description of router-id in the section “Configuring a virtual link” (page 222).
The no version restores the default value.
Use show ipv6 ospf3 virtual-link router-id to view the current setting.
See the example at “Viewing OSPFv3 virtual link information” (page 243).
Default: 10 seconds
