Using VLANs to Segregate Broadcast Domains
If you want to control the broadcasts on your network, use VLANs to create distinct broadcast
domains. Create one VLAN for each server subnet, and one for the router.
domains. Create one VLAN for each server subnet, and one for the router.
Configuration Example
This section describes the steps used to configure the example topology shown in
.
1.
Assign an IP address (or document the existing one) for each router and each server.
The following IP addresses are used:
2.
Assign an IP interface for each subnet attached to the switch.
Since there are four IP subnets connected to the switch, four IP interfaces are needed:
