Prisma SD-WAN supports using Open Shortest Path First (OSPF available in software version 6.4 and later) to manage network routes dynamically. OSPF is an interior gateway protocol (IGP) that simplifies routing for large enterprise networks at Branch sites, the Aggregation Layer on campus, and Data Center sites. The protocol determines routes dynamically by obtaining information from other routers and advertising them through Link State Advertisements (LSAs). Routers use the information collected from the LSAs to create and share a network topology map across the network, which populates the IP routing table.

OSPF simplifies network management and helps ensure high availability by dynamically adjusting routes to network changes.

To configure OSPF, you must enable L3 Direct Private WAN Forwarding, which allows your ION device to pair with an OSPF router via a private WAN interface. You must enable both L3 Direct Private WAN Forwarding and L3 LAN Forwarding to use dynamic LAN routing.
