Configure RIP on an Interface
Configure RIP parameters to control and optimize RIP routing for the interface.
Before you begin
Change the VRF instance as required to configure RIP on a specific VRF instance. The VRF must have an RP trigger of RIP. Not all parameters are configurable on non-default VRFs.
Procedure
- In the navigation pane, expand .
- Select RIP.
- Select the Interface Advance tab.
- Double-click a RIP parameter to edit it, as required.
- Select Apply.
Interface Advance Field Descriptions
Use the data in the following table to use the RIP Interface Advance tab.
|
Name |
Description |
|---|---|
|
Address |
Shows the address of the entry in the IP RIP interface table. |
|
Interface |
Indicates the index of the RIP interface. |
|
Enable |
Shows if the RIP interface is enabled or disabled. |
|
Supply |
Enables (true) or disables (false) the ability to send RIP updates on this interface. |
|
Listen |
Configures whether the switch learns routes on this interface. |
|
Poison |
Configures whether to advertise RIP routes learned from a neighbor back to the neighbor. If disabled, the interface invokes Split Horizon and does not advertise IP routes learned from an immediate neighbor back to the neighbor. If enabled, RIP poisons the RIP updates, sent to the neighbor from which a route is learned, with a metric of 16. Therefore, the receiver neighbor ignores this route because the metric 16 indicates infinite hops in the network. |
|
DefaultSupply |
Enables (true) or disables (false) an advertisement of a default route on this interface. This command takes effect only if a default route exists in the routing table. |
|
DefaultListen |
Enables (true) or disables (false) the switch to accept the default route learned through RIP on this interface. The default is disabled. Enable DefaultListen to add a default route to the route table if another route advertises it. |
|
TriggeredUpdate |
Enables (true) or disables (false) the switch to send RIP updates from this interface. |
|
AutoAggregate |
Enables (true) or disables (false) automatic route aggregation on this interface. If enabled, the switch automatically aggregates routes to their natural mask when an interface advertises them. The default is disabled. |
|
InPolicy |
Determines if RIP can learn routes on this interface. This variable also specifies the parameters of the route when RIP adds it to the routing table. |
|
OutPolicy |
Determines if RIP advertises a route from the routing table on this interface. This policy also specifies the parameters of the advertisement. |
|
Cost |
Indicates the RIP cost for this interface. The range is 1–15. The default is 1. |

Disabled (false) |
Disabled (false) |
Does not listen to RIP updates. |
||
|
Enabled (true) |
Disabled (false) |
Listens to all RIP updates except the default. |
||
|
Disabled (false) |
Enabled (true) |
Listens only to the default. |
||
|
Enabled (true) |
Enabled (true) |
Listens to RIP updates including the default route (if it exists). |
