Networking Requirements
As shown in Figure 3-5, VLAN 2 and VLAN 3 are combined into a super-VLAN, VLAN 4.
The sub-VLANs (VLAN 2 and VLAN 3) cannot ping each other.
After proxy ARP is configured, VLAN 2 and VLAN 3 can ping each other.

Configuration Roadmap
The configuration roadmap is as follows:
1. Add interfaces of the Router to sub-VLANs.
2. Add the sub-VLANs to the super-VLAN.
3. Configure the IP address for the super-VLAN.
4. Configure proxy ARP for the super-VLAN.
Data Preparation
To complete the configuration, you need the following data:
l Ethernet 2/0/1 and Ethernet 2/0/2 belong to VLAN 2.
l Ethernet 2/0/3 and Ethernet 2/0/4 belong to VLAN 3.
l The VLAN ID of the super-VLAN is 4.
l The IP address of the super-VLAN is 100.1.1.1.
Procedure
