Tuning And Optimizing Ospfv3 Networks; Prerequisites; Configuring Ospfv3 Timers - H3C S5800 Series Configuration Manual

Executing the import-route or default-route-advertise command on a router makes it become
an ASBR.
You can only inject and advertise a default route using the default-route-advertise command.
Since OSPFv3 is a link state routing protocol, it cannot directly filter LSAs to be advertised.
Therefore, you need to filter redistributed routes first, and thus only routes that are not filtered out
can be advertised in LSAs into the routing domain.
Use of the filter-policy export command filters routes redistributed with the import-route
command. If the import-route command is not configured, executing the filter-policy export
command does not take effect.

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
Use the command...
system-view
interface interface-type
interface-number
ospfv3 timer hello seconds
[ instance instance-id ]
9-12
