RIP

RIP (Routing Information Protocol) sends routing update messages at regular intervals and when the network topology changes. When a router receives a routing update that includes changes to an entry, it updates its routing table to reflect the new route. RIP routers maintain only the best route to a destination. After updating its routing table, the router immediately begins transmitting routing updates to inform other network routers of the change.

1. Select the RIP features that you want to enable or disable:
• General RIP Parameters:
• RIP mode—Globally enables or disables RIP.
• Auto summary—Summarizes information from all sub-networks. If Auto summary is disabled, RIP packets include sub-network information from individual sub-networks.
• Table of current Interface RIP parameter:
• Interface—The WAN interface to be configured.
• Operation Mode:

  Disable—RIP disabled on this interface.

  Enable—RIP enabled on this interface.

  Silent—Listens for route broadcasts and updates its route table. It does not participate in sending route broadcasts.

• Version—Sets the RIP version to use on this interface.
• Poison Reverse—A method for preventing loops that would cause endless retransmission of data traffic.
• Authentication Required:

None—No authentication.

Password—A password authentication key is included in the packet. If this does not match what is expected, the packet will be discarded. This method provides very little security as it is possible to learn the authentication key by watching RIP packets.

• Authentication Code: Password Authentication key.
