RIP

Selecting advanced RIP options

192
Advanced RIP options let you specify settings for RIP timers and define metrics
for redistributing routes that the FortiGate unit learns through some means other
than RIP updates. For example, if the FortiGate unit is connected to an OSPF or
BGP network or you add a static route to the FortiGate routing table manually, you
can configure the FortiGate unit to advertise those routes on RIP-enabled
interfaces.
To select advanced RIP options, go to Router > Dynamic > RIP and expand
Advanced Options. After you select the options, select Apply.
Note: Additional advanced options can be configured through the CLI. For example, you
can filter incoming or outgoing updates using a route map, an access list, or a prefix list.
The FortiGate unit also supports offset lists, which add the specified offset to the metric of a
route. For more information, see the "router" chapter of the
Figure 106:Advanced Options (RIP)
Default Metric Enter the default hop count that the FortiGate unit should assign
to routes that are added to the Fortinet routing table. The range is
from 1 to 16.
This value also applies to Redistribute unless otherwise specified.
Enable Default- Select to generate and unconditionally advertise a default route
into the FortiGate unit's RIP-enabled networks. The generated
information-originate
route may be based on routes learned through a dynamic routing
protocol, routes in the routing table or both.
RIP Timers Override the default RIP timer settings. The default settings are
effective in most configurations — if you change these settings,
take care to ensure that the new settings are compatible with local
routers and access servers.
Update
Timeout
FortiGate CLI
Enter the amount of time (in seconds) that the
FortiGate unit will wait between sending RIP
updates.
Enter the maximum amount of time (in seconds)
that a route is considered reachable while no
updates are received for the route. This is the
maximum time the FortiGate unit will keep a
reachable route in the routing table while no
updates for that route are received. If the FortiGate
unit receives an update for the route before the
timeout period expires, the timer is restarted.
The Timeout period should be at least three times
longer than the Update period.
