You can configure dynamic routing using Border Gateway Protocol (BGP) for a branch or data center. The configuration on a branch ION device is identical to a data center ION device with the exception of prefix advertisement in a branch and additional core and edge peers in a data center.

Configure dynamic Border Gateway Protocol (BGP) routing on a branch ION device for Internet, private WAN underlays, LAN and standard VPNs. The ION device learns routes dynamically from private WAN and standard VPN BGP peers and distributes to the LAN BGP peers. Routes learnt from LAN peers will be sent to the Prisma SD-WAN controller via API and to other LAN and private WAN BGP peers.

On a DC mode ION, you can configure dynamic routing only on those interfaces of the ION device, which are configured as—Peer with a Network or a standard VPN interface. ION devices in data centers do not support routing on interfaces configured as Use to Connect to Internet.

Prisma SD-WAN supports the Open Shortest Path First routing protocol with the Layer 3 switches on the LAN at Branch and DC sites.

OSPF is an interior gateway protocol (IGP) often used to manage network routes dynamically in large enterprise networks. It dynamically determines routes by obtaining information from other routers and advertising routes to other routers through Link State Advertisements (LSAs). The information gathered from the LSAs is used to construct a network topology map. This topology map is shared across routers in the network and used to populate the IP routing table with available routes.

Use the following steps to configure dynamic routing using BGP:
