Configuration Roadmap

The configuration roadmap is as follows:

1. Add two Ethernet interfaces to VLAN 100 in default mode.

2. Enable Layer 2 topology detection to view changes of ARP entries.

Data Preparation

To complete the configuration, you need the following data:

l Types and numbers of the interfaces to be added to a VLAN

l IP addresses of the VLANIF interface and the PCs

Procedure

Step 1 Create VLAN 100 and add the two Ethernet interfaces on the Router to VLAN 100 in default

mode.

# Create VLAN 100 and configure an IP addresses for the VLANIF interface.
