Optimizing OSPF Networks

Configuring OSPF Packet Timer

By changing the OSPF packet timer, you can adjust the convergence speed of the OSPF network and the network overload caused by protocol packets.

Configuring the Delay for Transmitting LSAs on the Interface

You can set the delay for transmitting LSAs on the interface according to the link rate.

Configuring the Interval for Updating LSA

To promote the route aggregation rate on the network, you can configure the interval for updating LSAs as required.

Configuring the Interval for Receiving LSAs

To make topology changes be sensed immediately, you can configure the interval for receiving LSAs as 0.

Configuring the Interval for SPF Calculation

Through the configuration of the interval for SPF calculation, the influence resulting from network changes can be restrained.

Suppressing the Interface from Receiving and Sending OSPF Packets

You can configure the interface so that the receiving and sending of OSPF packets are prohibited, and thus the networking adaptability of OSPF is enhanced and system resource consumption is reduced.

Configuring a Stub Router

You can configure the stub router to inform other OSPF routers that they cannot use the stub router to forward data.

Configuring the MTU in DD Packets

This describes how to configure the interface to fill in the Interface MTU field of the DD packets with the actual MTU value when the interface sends DD packets. By default, the MTU field of DD packets adopts 0.

Configuring the Maximum Number of External LSAs in the LSDB

By setting the maximum number of external LSAs in the LSDB, you can restrict the number of routes within a proper range.

Configuring RFC1583 Compatible External Routing

Because RFC2328 and RFC1583 adopt different route selection rules, you can configure the external route selection rules that are compatible with RFC1583.

Configuring OSPF Neighbor Relationship Flapping Suppression

OSPF neighbor relationship flapping suppression works by delaying OSPF neighbor relationship reestablishment or setting the link cost to the maximum value.
