Using EoIP Tunnels for Guest Services
Basic solutions use separate VLANs for guest and corporate users to segregate guest traf-
fic from corporate traffic. The guest SSID is broadcast, but the corporate SSID is not. All
other security parameters are configured. Another solution is to use Ethernet over IP
(EoIP) to tunnel the guest traffic from the CAPWAP to an anchor WLC.
As shown in Figure 5-17, EoIP is used to logically segment and transport guest traffic
from the edge AP to the anchor WLC. There is no need to define guest VLANs in the in-
ternal network, and corporate traffic is still locally bridged. The Ethernet frames from the
guest clients are maintained across the CAPWAP and EoIP tunnels.

Wireless Mesh for Outdoor Wireless
Tradit ionally, outdoor w irele s s s olut ion s have been limited to point-to-point and point-to-
multipoint bridging between buildings. With these solutions, each AP is wired to the net-
work. The Cisco wireless mesh networking solution, shown in Figure 5-18, eliminates the
need to wire each AP and allows users to roam from one area to another without having to
reconnect.
