Network Configurations
Both the RoamAbout Access Point 2000 and the R2 can be used as a wireless bridge to an
existing VLAN. For example, two APs can connect VLANs residing in different buildings,
as illustrated in Figure 2-4. The wired side of each AP is connected to a switch that
supports VLAN IDs. Switch 1 connects to VLANs Red, Blue, and Green, but only forwards
data from VLANs Red and Green. Switch 2, in a different building, connects to VLANs
Red and Green. The AP is configured to forward VLAN data.
Figure 2-4: Wireless Bridge Between VLANs
Figure 2-5 shows a point-to-multipoint configuration. Switch 1 connects to VLANs Red,
Blue, Green, and Purple. R2(E) is configured to forward data from VLAN Red to wireless
endpoint R2(A), VLAN Blue to R2(B), VLAN Green to R2(C), and VLAN Purple to
R2(D). This example is only valid for the RoamAbout R2.
