Configurable parameters
In the Nortel Switched Firewall 2.3.3, OSPF parameters can be configured through the
Command Line Interface (CLI) or Browser-Based Interface (BBI).
The CLI supports the following parameters: interface output cost, interface priority, dead and
hello intervals, retransmission interval, and interface transmit delay.
In addition, you can specify the
Shortest Path First (SPF) interval
—Time interval between
successive calculations of the shortest path tree using the Dijkstra’s algorithm.
