Dynamic Routing uses RIP ( Routing Information Protocol) for exchanging routing
information with other routers in the network.
The user can set the following parameters:
Enable : Enable/Disable RIP
Protocol : Choice of RIP version ( RIP v1/v2/Compatibility)
Enable Password: RIP version v2/Compatibility allows the user to provide simple
plaintext password based authentication to RIP packets.
Password : The 16 character long plaintext password.
Direction: Normally when RIP is enabled on a router it dynamically learns routes
on all it's configured interfaces. This parameter allows the user to select the interfaces
on which RIP is expected to learn and distribute routing information. This feature allows
the user to control how and which routes get distributed through the network e.g. prevent
routes to the private LAN networks from being sent over to the WAN side router.
On a per-interface basis the user can choose to
a) Both => Receive updates on the interface and also send it's routing table to other routers
connected to that interface.
b) In => Receive routing updates from other routers connected to that interface but NOT send
routing updates on that interface.
c) Out => Send routing updates but not receive updates on this interface from the other routers
connected to that interface
d) None => Ignores this interface and not send or receive routing updates through this interface.
Note: If the modem has multiple WAN connections and is expected to learn routes from WAN side
routers as well as route traffic between the WAN interfaces then NAT and Firewall services
should be disabled on all the relevant WAN interfaces.
