RIP is a distance-vector routing protocol intended for small, relatively homogeneous,
networks. RIP uses hop count as its routing metric. Each network is usually counted
as one hop. The network diameter is limited to 15 hops.
General
Figure 57: RIP General settings
RIP Version Enable sending and receiving RIP version 1 packets, RIP version 2
packets, or both for all RIP-enabled interfaces. You can override this
setting on a per interface basis. See “Interface options” on page 150 .
Default Metric For non-default routes in the static routing table and directly connected
networks the default metric is the metric that the FortiGate unit advertises
to adjacent routers. This metric is added to the metrics of learned routes.
The default metric can be a number from 1 to 16.
Enable Default-
information-
originate Advertise a default static route into RIP.
RIP Timers: RIP timer defaults are effective in most configurations. All routers and
access servers in the network should have the same RIP timer settings.
Update The time interval in seconds between RIP updates.
Garbage The time in seconds that must elapse after the timeout interval for a route
expires, before RIP deletes the route. If RIP receives an update for the
route after the timeout timer expires but before the garbage timer expires
then the entry is switched back to reachable.
Timeout The time interval in seconds after which a route is declared unreachable.
The route is removed from the routing table. RIP holds the route until the
garbage timer expires and then deletes the route. If RIP receives an
update for the route before the timeout timer expires, then the timeout
timer is restarted. If RIP receives an update for the route after the timeout
timer expires but before the garbage timer expires then the entry is
switched back to reachable. The value of the timeout timer should be at
least three times the value of the update timer.
Redistribute: Advertise routes learned from static routes, or a direct connection to the
destination network.
Connected Advertise routes learned from directly connected networks.
Metric Enter the metric to be used for the redistributed connected routes.
