Using VLANs to Segregate Broadcast Domains
In the previous example, devices that share a common IP network are all in the
same broadcast domain. If you want to limit the broadcasts on your network, you
could use VLANs to create distinct broadcast domains. For example, as shown in
the following procedure, you could create one VLAN for the client trunks, one for
the routers, and one for the servers.
In this example, you are adding to the previous configuration.
1.
Determine which switch ports and IP interfaces belong to which VLANs.
The following table adds port and VLAN information:
2.
Add the switch ports to their respective VLANs.
The VLANs shown in Table 35 are configured as follows:
