- Terminology
Distributed L2 Mode
In this mode, the W-IAP assigns an IP address from the configured subnet and forwards traffic to both
corporate and non-corporate destinations. Clients receive the corporate IP with Virtual Controller as the DHCP
server. The default gateway for the client still resides in the datacenter and hence this mode is an L2 extension
of corporate VLAN to remote site. Either the controller or an upstream router can be the gateway for the
clients. Client traffic destined to datacenter resources is forwarded by the Master AP (through the IPSec tunnel)
to the client's default gateway in the datacenter.
When a W-IAP registers with the controller, the controller automatically adds the VPN tunnel associated to this
W-IAP into the VLAN multicast table. This allows the clients connecting to the L2 mode VLAN to be part of the
same L2 broadcast domain on the controller.
Distributed L3 Mode
The distributed L3 mode contains all broadcast and multicast traffic to a branch. The distributed L3 mode
reduces the cost and eliminates the complexity associated with the classic site-to-site VPN. However, this mode
is very similar to a classic site-to-site IPsec VPN where two VPN endpoints connect individual networks together
over a public network.
In distributed L3 mode, each branch location is assigned a dedicated subnet. The master AP in the branch
manages the dedicated subnet and acts as the DHCP server and gateway for clients. Client traffic destined to
datacenter resources is routed to the controller through the IPsec tunnel, which then routes the traffic to the
appropriate corporate destinations.
When a W-IAP registers with the controller, the Controller adds a route to enable the routing of traffic from the
corporate network to clients on this subnet in the branch.
Centralized L2 Mode
The centralized L2 mode extends the corporate VLAN or broadcast domain to remote branches. The DHCP
server and the gateway for the clients reside in the datacenter. Either the controller or an upstream router can
be the gateway for the clients. For DHCP services in centralized L2 mode, it is recommended that you use an
external DHCP server and not the DHCP server on the controller. Client traffic destined to datacenter
resources is forwarded by the master W-IAP (through the IPsec tunnel) to the client's default gateway in the
datacenter.
Centralized L3 Mode
For centralized L3 clients, the virtual controller acts as a DHCP relay agent that forwards the DHCP traffic to the
DHCP server located behind the controller in the corporate network and reachable through the IPSec tunnel.
The centralized L3 VLAN IP is used as the source IP. The IP address is obtained from the DHCP server.
