OSPF (Open Shortest Path First) is a link-state routing protocol that is not proprietary to any vendor or organization. OSPF was developed by IETF (Internet Engineering Task Force), and it is the IGP (Interior Gateway Protocol) recommended by Pica8.
OSPF has evolved through several RFCs. OSPF version 2, which is the current version for IPv4, is defined in RFC 2328. PicOS supports version 2 of the OSPF protocol in L2/L3 mode.
Pica8 PicOS Version 2.6 supports the following OSPF area types:
- Normal Area
- Stub Area
- NSSA (Not-So-Stubby Area)
NOTE:
Enable IP routing function before using this feature, for details please refer to Configuring IP Routing.
