Configuring RIP interface compatibility

Configure RIP parameters on an interface so you can control RIP behavior on the interface. You can specify the RIP version to use on interfaces that you configure to send (supply) or receive (listen to) RIP updates.

Before you begin

  • Configure a routing interface (either a router port or a virtual routing interface).

  • Assign an IP address to the interface.

  • Enable RIP globally.

  • 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.

About this task

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

Although visible, the switch does not support the AuthType and AuthKey parameters.

Procedure

  1. In the navigation pane, expand Configuration > IP.
  2. Click RIP.
  3. Click the Interface tab.
  4. Double-click the Send value to edit it, and then select the RIP version datagrams the router sends.
  5. Double-click the Receive value to edit it, and then select the RIP version datagrams for which the router listens.
  6. Click Apply.

Interface Field Descriptions

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

Name

Description

Address

Specifies the IP address of the router interface.

Domain

Specifies the value inserted into the routing domain parameter of all RIP packets sent on this interface.

AuthType

Specifies the type of authentication to use on this interface.

AuthKey

Specifies the authentication key whenever AuthType is not noAuthentication.

Send

Specifies the update version the router sends on this interface:

  • DoNotSend—no RIP updates sent on this interface

  • ripVersion1—RIP updates compliant with RFC1058

  • rip1Compatible—broadcast RIPv2 updates using RFC1058 route subassumption rules

  • ripVersion2—multicast RIPv2 updates

The default is rip1compatible.

Receive

Indicates which versions of RIP updates to accept:

  • rip1

  • rip2

  • rip1OrRip2

The default is rip1OrRip2. Rip2 and rip1OrRip2 imply receipt of multicast packets.

Job Aid

Choose one of three options for receiving RIP updates:

  • rip1OrRip2—accepts RIPv1 or RIPv2 updates

  • rip1—accepts RIPv1 updates only

  • rip2—accepts RIPv2 updates only

The following table describes the four RIP send modes that the switch supports. You can configure RIP send modes on all router interfaces.

Table 1. RIP send modes

Send mode

Description

Result

rip1Compatible

Broadcasts RIPv2 updates using RFC1058 route consumption rules.

This is the default mode.

  • Destination MAC is a broadcast, ff-ff-ff-ff-ff-ff

  • Destination IP is a broadcast for the network (for example, 192.0.2.255)

  • RIP update is formed as a RIP-2 update, including network mask

  • RIP version = 2

ripVersion1

Broadcasts RIP updates that are compliant with RFC1058

  • Destination MAC is a broadcast, ff-ff-ff-ff-ff-ff

  • Destination IP is a broadcast for the network (for example, 198.0.2.255)

  • RIP update is formed as a RIP-1 update, no network mask included

  • RIP version = 1

ripVersion2

Broadcasts multicast RIPv2 updates

  • Destination MAC is a multicast, 01-00-5e-00-00-09

  • Destination IP is the RIP-2 multicast address, 224.0.0.9

  • RIP update is formed as a RIP-2 update including network mask

  • RIP version = 2

doNotSend

Does not send RIP updates on the interface

None
