The FIB may also include routes that are not in the routing table - such as dynamically added routes to reach SSL-VPN users.Entries contain interface identifier and next hop information for each reachable destination network prefix.It is a table that contains information necessary to forward IP datagrams - ALL active routes in the routing table must be present in the FIB.The RIB is the input to the route computation.Every protocol such as OSPF, EIGRP, BGP has its own RIB and select their best candidates to try to install to global RIB so that it can then be selected for forwarding. RIB is derived from the control plane, it is not used for forwarding.This is a database of routing prefixes that could potentially be installed into the forwarding table.Packets are forwarded according to the forwarding table.This includes directly connected, static routes and dynamically learned routes. The routing table manager then determines which route for a particular destination is to be submitted to the forwarding table.All IP routing protocols submit their best routes for each destination to the routing table.View routing information on FortiGate CLI This article describes how to view routing information.
