Figure 4 RIP Configuration
The following configuration only shows the operations related to RIP. Before
performing the following configuration, verify that the Ethernet link layer works
normally.
1 Configure RIP on Switch A:
[Switch A] rip
[Switch A-rip] network 110.11.2.0
[Switch A-rip] network 155.10.1.0
2 Configure RIP on Switch B:
[Switch B] rip
[Switch B-rip] network 196.38.165.0
[Switch B-rip] network 110.11.2.0
3 Configure 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 7700 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.
OSPF
Open Shortest Path First (OSPF) is an Interior Gateway Protocol (IGP). At present,
OSPF version 2 (RFC2328) is used, which has the following features:
