Configuring Dynamic Routing - RIP
Use the Networking > Routing > Dynamic - RIP page to configure Dynamic Routing
or RIP. 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 At the top of the page, 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, specif y the RIP version. The security
appliance supports RIP Version 1 and RIP Version 2.
-RIP Version 1 is a class-based routing version that does not include
subnet information. This is the most commonly supported version.
-RIP Version 2 includes all the functionality of RIPv1 plus it supports
subnet information.
-Default: The data is sent in RIP Version 1 format and received in RIP
Version 1 and 2 format. This is the default setting.
STEP 2 In the table, specify the RIP settings for each available interface:
RIP Enable: Check this box to enable the RIP settings on the port or VLAN.
Authentication: If you are using RIP Version 2, click the Edit (pencil) icon to
specify the authentication method for the port or VLAN.
-None: Choose this option to invalidate the authentication.
-Simple Password Authentication: Choose this option to validate the
simple password authentication. Enter the password in the field.
-MD5 Authentication: Choose this option to validate the MD5
authentication. Enter the unique key ID in the MD5 Key ID field and the
Key in the MD5 Auth Key field.
Port Passive: Determines how the security appliance receives RIP packets.
Check this box to enable this feature on the port or VLAN.
STEP 3 Click Save to apply your settings.
