Configuring RIP on a port

Configure RIP on a port so that the port can participate in RIP routing.

Before you begin

  • Assign an IP address to the port.

  • Configure RIP and enable it globally.

    Both brouter ports and VLAN virtual routing interfaces use the same RIP global parameters.

  • Enable RIP on the interface.

About this task

On an interface, RIP does not operate until you enable it globally and on the interface.

Procedure

  1. In the Device Physical View tab, select a port.
  2. In the navigation pane, expand Configuration > Edit > Port.
  3. Click IP.
  4. Click the RIP tab.
  5. Configure the RIP parameters as required.
  6. Click Apply.

RIP field descriptions

Use the data in the following table to use the RIP tab.

Name

Description

Enable

Enables or disables RIP on the port.

Supply

Specifies that the routing switch advertises RIP routes through the interface. The default is enable.

Listen

Specifies that the routing switch learns RIP routes through this interface. The default is enable.

Poison

If disabled, the interface invokes Split Horizon and does not advertise IP routes learned from an immediate neighbor back to the neighbor. If enabled, the RIP update sent to a neighbor from which a route is learned is poisoned with a metric of 16. In this manner, the route entry is not passed to the neighbor, because 16 is infinity in terms of hops on a network. The default is disable.

DefaultSupply

Enables or disables DefaultSupply. Enable DefaultSupply if a default route exists in the routing table. The default is false.

RIP advertises the default route only if it exists in the routing table.

DefaultListen

Enables or disables DefaultListen. Enable DefaultListen if this interface must learn a default route after another router that connects to the interface advertises it. The default is false (disabled).

Enable DefaultListen to add a default route to the route table if another router advertises it.

TriggeredUpdateEnable

Enables or disables triggered RIP updates. The default is false (disabled).

AutoAggregateEnable

Enables or disables RIP automatic aggregation. RIPv2 automatically aggregates routes to their natural mask. You can enable automatic aggregation only in RIPv2 mode or RIPv1 compatibility mode. The default is false.

AdvertiseWhenDown

Enables or disables AdvertiseWhenDown. If true, RIP advertises the network on this interface as up, even if the port is down. The default is false.

If you configure a port with no link and enable AdvertiseWhenDown, the port does not advertise the route until the port is active. RIP advertises the route even when the link is down. To disable advertising based on link-states, disable AdvertiseWhenDown.

InPolicy

Determines whether the RIP can learn a route on this interface. This variable also specifies the parameters of the route when RIP adds it to the routing table.

OutPolicy

Determines if this interface 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 default is 1, and the range is 1–15.

HolddownTime

Configures the length of time that RIP continues to advertise a network after determining it is unreachable. The range is 0–360 seconds. The default is 120 seconds

TimeOutInterval

Configures the RIP timeout interval in seconds. The range is 15–259200 seconds. The default is 180 seconds.
