Routing Information Protocol Configuration
The Routing Information Protocol (RIP) is an interior gateway protocol (IGP). RIP is one of a class of algorithms known as a distance vector algorithm. The distance or hop count is used as the metric to determine the best path to a remote network or host where the hop count does not exceed 15 hops, assuming a cost of one for each network. RIP uses broadcast User Datagram protocol (UDP) data packets to exchange routing information.
RIP sends routing information updates every 30 seconds. This update contains known networks and the distances (hop count) associated with each hop. For RIP1, no mask information is exchanged — the natural mask is always applied by the router receiving the update. For RIP2, mask information is sent.
There are two timers associated with each route: a timeout, and a garbage-collection timer. Upon expiration of the timeout timer, the route is no longer valid but it is retained in the routing table for a short time so that neighbors can be notified that the route has been dropped. Upon expiration of the garbage-collection timer, the route is finally removed from the routing table. The timeout timer is set for 180 seconds, and the garbage-collection timer is set for 120 seconds by default.
This menu is used for configuring globally RIP parameters. RIP is turned off by default.

Command Syntax and Usage |
---|
if <Interface Number (1-256)> |
| Displays the RIP Interface menu. To view this menu, see /cfg/l3/rip/if RIP Interface Menu. Default: enable |
update <update period (1-120 seconds)> |
| Sets the RIP update period. Default: 30 seconds |
redist |
| |
vip disable|enable |
| Enables or disables the advertisement of virtual IP addresses as host routes. If a VIP route exists in a routing table, it is always advertised except when it is included in another network route that is already being advertised. Note: If all real servers behind a VIP go down, the route gets removed from the routing table, and is not advertised. If you disable all the real servers using an operation command, the VIP route does not get eliminated from the routing table, and Alteon continues to advertise the route. |
statc disable|enable |
| Enables or disables the advertisement of static routes. |
on |
| Globally turns RIP on. |
off |
| Globally turns RIP off. |
cur |
| Displays the current RIP configuration. |
