Configuring 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

  1. In the navigation pane, expand Configuration > IP.
  2. Click RIP.
  3. Click the Interface Advance tab.
  4. Double-click a RIP parameter to edit it, as required.
  5. Click 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.

Job aid

The following table indicates the relationship between switch action and the RIP supply and listen settings.

Disabled (false)

Disabled (false)

Sends no RIP updates.

Enabled (true)

Disabled (false)

Sends RIP updates except the default.

Disabled (false)

Disabled (false)

Sends only the default (default route must exist in routing table).

Enabled (true)

Enabled (true)

Sends RIP updates including the default route (if it exists).

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).
