Example 2, VLANs Across Multiple Switches

5.The switch adds the source MAC address and VLAN for station R2 to its Source Address Table in FDB ID 2, and checks the Source Address Table for the destination MAC address given in the frame. The switch finds the MAC address and VLAN in this table, and recognizes that the MAC address and VLAN match for R1 is located out Port 1.

6.The switch examines its VLAN configuration information and determines that the frame for Red VLAN is allowed to be forwarded out Port 1 and that it must be sent in an untagged format.

7.The switch forwards the frame out Port 1. Any other unicast transmissions between stations R1 and R2 will be handled identically.

12.13 EXAMPLE 2, VLANs ACROSS MULTIPLE SWITCHES

This second example investigates the steps that must be taken to set up VLANs across multiple 802.1Q VLAN switches. This includes the configuration and operation of trunk ports (port set for TAGGED frames only) between 802.1Q VLAN switches.

As shown in Figure 12-12, two companies, “Redco” and “Blue Industries,” share floors 2 and 4 in a building where the network infrastructure is supplied by the building owner. The objective is to completely isolate the network traffic of the two companies by limiting the user’s traffic through the ports of two switches, thus maintaining security and shielding the network traffic from each company. This example will show the use and configuration of a trunk connection and the creation of VLANs across multiple switches.
