OSPF Overview
Open Shortest Path First (OSPF) is a link-state routing protocol that supports IP
subnetting and authentication. The SSR supports OSPF Version 2.0 as defined in RFC
1583. Each link-state message contains all the links connected to the router with a
specified cost associated with the link.
The SSR supports the following OSPF functions:
• Stub Areas: Definition of stub areas is supported
• Authentication: Simple password and MD5 authentication methods are supported
within an area
• Virtual Links: Virtual links are supported
• Route Redistribution: Routes learned via RIP, BGP, or any other sources can be
redistributed into OSPF. OSPF routes can be redistributed into RIP or BGP
• Interface Parameters: Parameters that can be configured include interface output cost,
retransmission interval, interface transmit delay, router priority, router dead and hello
intervals, and authentication key
