Configuration Roadmap
The configuration roadmap is as follows:
1. Add the interface connecting RouterA and branch A to VLAN 10 and add the interface
connecting RouterB and branch B to VLAN 20.
2. Enable routed proxy ARP on VLANIF interfaces of branch A and branch B to implement
communication between the two branches.
Data Preparation
To complete the configuration, you need the following data:
l Ethernet0/0/0 connecting RouterA and branch A
l Ethernet0/0/0 connecting RouterB and branch B
l IP address 172.16.1.1/24 of VLANIF 10
l MAC address 00e0-fc39-80aa of VLANIF 10
l IP address 172.16.2.1/24 of VLANIF 20
l MAC address 00e0-fc39-80bb of VLANIF 20
Procedure
Step 1 Configure RouterA.
# Create VLAN 10.
<Huawei> system-view
[Huawei] sysname RouterA
[RouterA] vlan 10
[RouterA-vlan10] quit
# Add Ethernet0/0/0 to VLAN 10.
[RouterA] interface ethernet 0/0/0
[RouterA-Ethernet0/0/0] port link-type access
[RouterA-Ethernet0/0/0] port default vlan 10
[RouterA-Ethernet0/0/0] quit
# Configure an IP address for VLANIF 10.
[RouterA] interface vlanif 10
[RouterA-Vlanif10] ip address 172.16.1.1 255.255.255.0
# Enable routed proxy ARP on VLANIF 10.
[RouterA-Vlanif10] arp-proxy enable
[RouterA-Vlanif10] quit
Step 2 Configure RouterB.
The configuration of RouterB is similar to that of RouterA.
Step 3 Verify the configuration.
# Select host A at 172.16.1.2/16 in branch A and select host B at 172.16.2.2/16 in branch B.
Ping the IP address of host B from host A.
C:\Documents and Settings\Administrator>ping 172.16.2.2
