Router Dynamic
This section explains how to configure dynamic protocols to route traffic through
large or complex networks. Dynamic routing protocols enable the FortiGate unit to
automatically share information about routes with neighboring routers and learn
about routes and networks advertised by neighboring routers. The FortiGate unit
supports these dynamic routing protocols:
• Routing Information Protocol (RIP)
• Open Shortest Path First (OSPF)
• Border Gateway Protocol (BGP)
Note: Basic RIP, OSPF, and BGP routing options can be configured through the web-based
manager. Many additional options may be configured through CLI commands only. For
complete descriptions and examples of how to use CLI commands to configure RIP, OSPF,
and BGP settings, see the “router” chapter of FortiGate CLI Reference.
The FortiGate unit selects routes and updates its routing table dynamically based
on the rules you specify. Given a set of rules, the FortiGate unit can determine the
best route or path for sending packets to a destination. You can also define rules
to suppress the advertising of routes to neighboring routers and/or change
FortiGate routing information before it is advertised.
Note: A FortiGate unit can operate as a Protocol Independent Multicast (PIM) version 2
router in the root virtual domain. FortiGate units support PIM sparse mode and dense mode
and can service multicast servers or receivers on the network segment to which a FortiGate
interface is connected. PIM can use static routes, RIP, OSPF, or BGP to forward multicast
packets to their destinations.
Bi-Directional Forwarding (BFD) is a protocol that works with BGP and OSPF to
quickly discover routers on the network that can not be contacted, and re-route
traffic accordingly until those routers can be contacted.
This section describes:
• RIP
• OSPF
• BGP
• Multicast
• Bi-directional Forwarding Detection (BFD)
