Configuring Dynamic Routing
RIP (Routing Information Protocol, RFC 2453) is an Interior Gateway Protocol (IGP)
that is commonly used in internal networks. It allows the Cisco RV180/RV180W 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.
NOTE RIP is disabled by default on the Cisco RV180/RV180W.
To configure dynamic routing:
STEP 1 Choose Networking > Routing > Dynamic Routing.
STEP 2 To configure how the firewall sends and receives RIP packets, choose the RIP
direction:
NoneThe firewall neither broadcasts its route table nor does it accept any
RIP packets from other routers. This option disables RIP.
In OnlyThe firewall accepts RIP information from other router, but does not
broadcast its routing table.
Out OnlyThe firewall broadcasts its routing table periodically but does not
accept RIP information from other routers.
BothThe firewall both broadcasts its routing table and also processes RIP
information received from other routers.
STEP 3 Choose the RIP version:
Disabled.
RIP-1This is a class-based routing version that does not include subnet
information. RIP-1 is the most commonly supported version.
RIP-2BThis version broadcasts data in the entire subnet.
RIP-2MThis version sends data to multicast addresses.
STEP 4 RIP v2 authentication forces authentication of RIP packets before routes are
exchanged with other routers. It acts as a security feature because routes are
exchanged only with trusted routers in the network. RIP authentication is disabled
by default. You can enter two key parameters so that routes can be exchanged
with multiple routers present in the network. The second key also acts as a failsafe
when authorization with first key fails. To enable authentication for RIP-2B or RIP-
