Configures the timers for all interfaces in the same OSPFv3 (Open Shortest Path First version 3) area.
vlan_name | Specifies an IPv6 configured VLAN (Virtual LAN). |
tunnel_name | Specifies an IPv6 tunnel. |
all | Specifies all IPv6 configured VLANs or all IPv6 tunnels. |
retransmit_interval | Specifies the length of time that the router waits before retransmitting an LSA that is not acknowledged. The range is 1 to 3600 seconds. |
transit_delay | Specifies the length of time it takes to transmit an LSA packet over the interface. The range is 1 to 3600 seconds. |
hello_interval | Specifies the interval at which routers send hello packets. The range is 1 to 65535 seconds. |
dead_interval | Specifies the interval after which a neighboring router is declared down due to the fact that hello packets are no longer received from the neighbor. The range is 1 to 65535 seconds. |
Use this command to configure the OSPFv3 timers on a per-interface basis.
The value of the dead interval and the hello interval must be same for all OSPFv3 routers connected to a common link. The value of the dead interval and the hello interval are advertised by OSPFv3 in Hello packets. The shorter the hello interval, the earlier topological changes will be detected, but more routing traffic will ensue.
The retransmit interval must be greater than the expected round trip delay between any two routers on the attached network. The setting of this parameter must be conservative, or needless retransmission will result.
Note
The wait interval for the interface is not separately configurable. It is always equal to the dead interval.The following command sets the timers for the VLAN corporate:
configure ospfv3 vlan corporate timer retransmit-interval 10 transit-delay 2 hello-interval 20 dead-interval 80
