OSPF Implementation in Alteon OS

Alteon OS supports a single instance of OSPF and up to 4 K routes on the network. The follow- ing sections describe OSPF implementation in Alteon OS:

„“Configurable Parameters” on page 193

„“Defining Areas” on page 194

„“Interface Cost” on page 196

„“Electing the Designated Router and Backup” on page 196

„“Summarizing Routes” on page 196

„“Default Routes” on page 197

„“Virtual Links” on page 198

„“Router ID” on page 199

„“Authentication” on page 199

Configurable Parameters

In Alteon OS, OSPF parameters can be configured through the Command Line Interfaces (CLI/ISCLI), Browser-Based Interface (BBI), or through SNMP. For more information, see Chapter 1, “Accessing the Switch.”

The CLI supports the following parameters: interface output cost, interface priority, dead and hello intervals, retransmission interval, and interface transmit delay.

In addition to the above parameters, you can also specify the following:

„Shortest Path First (SPF) interval—Time interval between successive calculations of the shortest path tree using the Dijkstra’s algorithm.

„Stub area metric—A stub area can be configured to send a numeric metric value such that all routes received via that stub area carry the configured metric to potentially influence routing decisions.

„Default routes—Default routes with weight metrics can be manually injected into transit areas. This helps establish a preferred route when multiple routing devices exist between two areas. It also helps route traffic to external networks.
