  Chapter 20: OSPF

BMD00220, October 2010

BLADEOS supports a single instance of OSPF and up to 4K routes on the network. The following 
sections describe OSPF implementation in BLADEOS:

In BLADEOS, OSPF parameters can be configured through the Command Line Interfaces 
(CLI/ISCLI), Browser-Based Interface (BBI), or through SNMP. For more information, see 

The ISCLI 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.

Passive—When enabled, the interface sends LSAs to upstream devices, but does not otherwise 
participate in OSPF protocol exchanges.

Point-to-Point—For LANs that have only two OSPF routing agents (the G8124 and one other 
device), this option allows the switch to significantly reduce the amount of routing information 
it must carry and manage.
