SonicOS 5.8.1 Administrator Guide
Note Be sure the device sending RIPv2 updates uses multicast mode, or the updates will not be
processed by the ars-rip router.
Send (Available in ‘Send and Receive’ and ‘Send Only’ modes)
• RIPv1 – Send broadcast RIPv1 packets.
• RIPv2 - v1 compatible – Send multicast RIPv2 packets that are compatible with RIPv1.
• RIPv2 – Send multicast RIPv2 packets.
Split Horizon – Enabling S
plit Horizon will suppress the inclusion of routes sent in updates to
routers from which they were learned. This is a common RIP mechanism for preventing routing
loops. See the ‘maximum hops’ entry at the start of Advanced Routing Services section.
Poisoned Reverse – Poison reverse is an optional mode of Split Horizon operation. Rather than
suppressing the inclusion of learned routes, the routes are sent with a metric of infinity (16) thus
indicating that they are unreachable. See the ‘maximum hops’ entry at the start of Advanced
Routing Services section.
Use Password – Enables the use of a plain-text password on this interface, up to 16 alpha-
numeric characters long, for identification.
Default Metric – Used to specify the metric that will be used when redistributing routes from
other (Default, Static, Connected, OSPF, or VPN) routing information sources. The default
value (undefined) is 1 and the maximum is 15.
Administrative Distance – The administrative distance value is used by routers in selecting a
path when there is more than one route to a destination, with the smaller distance being
preferred. The default value is 120, minimum is 1, and maximum is 255.
Originate Default Route – This checkbox enables or disables the advertising of the
SonicWALL’s default route into the RIP system.
Redistribute Static Routes – Enables or disables the advertising of static (Policy Based
Routing) routes into the RIP system. The metric can be explicitly set for this redistribution, or it
can use the value (default) specified in the ‘Default Metric’ setting.
Redistribute Connected Networks - Enables or disables the advertising of locally connected
networks into the RIP system. The metric can be explicitly set for this redistribution, or it can
use the value (default) specified in the ‘Default Metric’ setting.
Redistribute OSPF Routes - Enables or disables the advertising of routes learned via OSPF
into the RIP system. The metric can be explicitly set for this redistribution, or it can use the value
(default) specified in the ‘Default Metric’ setting.
Redistribute Remote VPN Networks - Enables or disables the advertising of static (Policy
Based Routing) routes into the RIP system. The metric can be explicitly set for this
redistribution, or it can use the value (default) specified in the ‘Default Metric’ setting.
Routes learned via RIP will appear in the Route Policies table as OSPF or RIP route.
Configuring OSPF
Note OSPF design concepts are beyond the scope of this document. The following section
describes how to configure a SonicWALL to integrate into an OSPF network, be it existing
or newly implemented, but it does not offer design guidelines. For terms used throughout
this section, refer to the ‘OSPF Terms’ section above.
