Tuning And Optimizing Ospfv3 Networks; Prerequisites; Configuring Ospfv3 Timers - 3Com S7906E Configuration Manual

Tuning and Optimizing OSPFv3 Networks

This section describes configurations of OSPFv3 timers, interface DR priority, MTU check ignorance for
DD packets, and disabling interfaces from sending OSPFv3 packets.
OSPFv3 timers:
Packet timer: Specified to adjust topology convergence speed and network load
LSA delay timer: Specified especially for low-speed links
SPF timer: Specified to protect networks from being over-loaded due to frequent network changes.
For a broadcast network, you can configure DR priorities for interfaces to affect DR/BDR election.
By disabling an interface from sending OSPFv3 packets, you can make other routers on the network
obtain no information from the interface.

Prerequisites

Enable IPv6 packet forwarding
Configure OSPFv3 basic functions

Configuring OSPFv3 Timers

Follow these steps to configure OSPFv3 timers:
To do...
Enter system view
Enter interface view
Configure the hello interval
Specify the poll interval
Configure the dead interval
Configure the LSA
retransmission interval
Configure the LSA
transmission delay
Return to system view
Enter OSPFv3 view
Use the command...
system-view
interface interface-type
interface-number
ospfv3 timer hello seconds
[ instance instance-id ]
ospfv3 timer poll seconds
[ instance instance-id ]
ospfv3 timer dead seconds
[ instance instance-id ]
ospfv3 timer retransmit
interval [ instance instance-id ]
ospfv3 trans-delay seconds
[ instance instance-id ]
quit
ospfv3 [ process-id ]
1-12
