98CHAPTER 5: IP ROUTING PROTOCOL OPERATION

Example: Typical RIP Configuration

As shown in Figure 25, the Switch C connects to the subnet 117.102.0.0 through the Ethernet port. The Ethernet ports of Switch A and Switch B are connected to the network 155.10.1.0 and 196.38.165.0. Switch C, Switch A, and Switch B are connected by Ethernet 110.11.2.0. Correctly configure RIP to ensure that Switch C, Switch A, and Switch B can interconnect.

The following configuration only shows the operations related to RIP. Before performing the following configuration, verify that the Ethernet link layer works normally.

1Configure RIP on Switch A:

[Switch A]rip

[Switch A-rip]network 110.11.2.0

[Switch A-rip]network 155.10.1.0

2Configure RIP on Switch B:

[Switch B]rip

[Switch B-rip]network 196.38.165.0

[Switch B-rip]network 110.11.2.0

3Configure RIP on Switch C:

[Switch C]rip

[Switch C-rip]network 117.102.0.0

[Switch C-rip]network 110.11.2.0

Troubleshooting RIP The Switch 7750 cannot receive update packets when the physical connection to the peer routing device is normal.

RIP does not operate on the corresponding interface (for example, if the undo rip work command is executed) or this interface is not enabled through the network command.

The peer routing device is configured for multicast mode (for example, the rip version 2 multicast command is executed) but the multicast mode has not been configured on the corresponding interface of the local Ethernet switch.
