1 Example for Configuring Basic RIP Functions
Networking Requirements
In Figure 1, SwitchA, SwitchB, SwitchC, and SwitchD are located on a small-sized network and need to communicate with each other.

Configuration Roadmap
RIP-2 is recommended if the network size is small. The configuration roadmap is as follows:
1. Configure VLAN and IP address for each interface to ensure network reachability.
2. Enable RIP on each switch to implement network connections between processes.
3. Configure RIP-2 on each switch to improve RIP performance.
Procedure
- Configure VLANs and add interfaces to the VLANs. The configurations of SwitchB, SwitchC, and SwitchD are similar to the configuration of SwitchA, and are not mentioned here.
<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan 10
[SwitchA-vlan10] quit
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] port link-type trunk
[SwitchA-GigabitEthernet1/0/1] port trunk allow-pass vlan 10
[SwitchA-GigabitEthernet1/0/1] quit
Configure an IP address to each VLANIF interface. The configurations of SwitchB, SwitchC, and SwitchD are similar to the configuration of SwitchA, and are not mentioned here.
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 192.168.1.1 24
[SwitchA-Vlanif10] quit
- Configure basic RIP functions.
# Configure SwitchA.
[SwitchA] rip
[SwitchA-rip-1] network 192.168.1.0
[SwitchA-rip-1] quit
# Configure SwitchB.
[SwitchB] rip
[SwitchB-rip-1] network 192.168.1.0
[SwitchB-rip-1] network 172.16.0.0
[SwitchB-rip-1] network 10.0.0.0
[SwitchB-rip-1] quit
# Configure SwitchC.
[SwitchC] rip
[SwitchC-rip-1] network 172.16.0.0
[SwitchC-rip-1] quit
# Configure SwitchD.
[SwitchD] rip
[SwitchD-rip-1] network 10.0.0.0
[SwitchD-rip-1] quit
# Check the RIP routing table of SwitchA.
[SwitchA] display rip 1 route
Route Flags : R - RIP
A - Aging, G - Garbage-collect
----------------------------------------------------------------------------
Peer 192.168.1.2 on Vlanif10
Destination/Mask Nexthop Cost Tag Flags Sec
172.16.0.0/16 192.168.1.2 1 0 RA 14
10.0.0.0/8 192.168.1.2 1 0 RA 14
The command output shows that the routes advertised by RIP-1 use natural masks.
- Configure the RIP version.
# Configure RIP-2 on SwitchA.
[SwitchA] rip
[SwitchA-rip-1] version 2
[SwitchA-rip-1] quit
# Configure RIP-2 on SwitchB.
[SwitchB] rip
[SwitchB-rip-1] version 2
[SwitchB-rip-1] quit
# Configure RIP-2 on SwitchC.
[SwitchC] rip
[SwitchC-rip-1] version 2
[SwitchC-rip-1] quit
# Configure RIP-2 on SwitchD.
[SwitchD] rip
[SwitchD-rip-1] version 2
[SwitchD-rip-1] quit
- Verify the configuration.
# Check the RIP routing table of SwitchA.
[SwitchA] display rip 1 route
Route Flags : R - RIP
A - Aging, G - Garbage-collect
----------------------------------------------------------------------------
Peer 192.168.1.2 on Vlanif10
Destination/Mask Nexthop Cost Tag Flags Sec
172.16.1.0/24 192.168.1.2 1 0 RA 32
10.1.1.0/24 192.168.1.2 1 0 RA 32
From the routing table, you can find that the routes advertised by RIP-2 contain more accurate subnet masks.
