IPv6 Configuration Guide K/KA/KB.15.15

Hello interval per interface
Syntax:
ipv6 ospf3 hello-interval 1 - 65535
Used in the VLAN context to indicate the length of time between the transmission
of hello packets from the routing switch to adjacent neighbors on that VLAN.
This command assigns the specified Hello interval to all networks configured on the
VLAN.
Default: 10 seconds
Priority per interface
Syntax:
ipv6 ospf3 priority 1 - 255
Used in the VLAN context to enable changing the priority of an OSPFv3 router. The
priority is used when selecting the designated router (DR) and backup designated
routers (BDRs).
The value can be from 0 to 255 (with 255 as the highest priority). If you set the
priority to 0, the routing switch does not participate in DR and BDR election.
This command assigns the specified priority to all networks configured on the VLAN.
Default: 1
Retransmit interval per interface
Syntax:
ipv6 ospf3 retransmit-interval 1 - 3600
Used in the VLAN context to enable changing the retransmission interval for link-state
advertisements (LSAs) on an interface.
Default: 5 seconds
Transit delay per interface
Syntax:
ipv6 ospf3 transit-delay 1 - 3600
Used in the VLAN context to enable changing the time it takes to transmit link state
update packets on this interface.
This command reconfigures the estimated number of seconds it takes to transmit a
link state update packet to all networks configured on the VLAN.
Default: 1 second
Configuring a virtual link
For more information, see “About configuring an ABR to use a virtual link to the backbone”
(page 260).
Syntax:
[no] area area-id virtual-link router-id
In the ospf3 context, used on a pair of ABRs at opposite ends of a virtual link in the same area to
configure the virtual link connection.
