Configuring the Dynamic Routing
Dynamic Routing or RIP, is an Interior Gateway Protocol (IGP) that is commonly
used in internal networks. It allows a router to exchange its routing information
automatically with other routers, and allows it to dynamically adjust its routing
tables and adapt to changes in the network.
STEP 1 Click Networking -> Routing -> Dynamic-RIP.
The Dynamic-RIP window opens.
STEP 2 Enter the following information:
• RIP Enable: Click On to enable RIP, or click Off to disable it. By default, RIP
is disabled.
• RIP Version: If you enable RIP, specify the RIP version. The security
appliance supports RIPv1 and RIPv2.
- RIPv1 is a class-based routing version that does not include subnet
information. This is the most commonly supported version.
- RIPv2 includes all the functionality of RIPv1 plus it supports subnet
information.
- Default: The data is sent in RIPv1 format and received in RIPv1 and RIPv2
format. This is the default setting.
STEP 3 Specify the RIP setting for each available interface:
• RIP Enable: Check this box to enable the RIP settings on the interface or
VLAN.
