Configure VPN Concentrators

The Tunnel Concentrator is effectively the IPv4 address of the tunnel termination point. Tunnel Concentrators are used with Generic Routing Encapsulation (GRE) tunnels to offer direct point-to-point traffic flow without involving the controller. The VPN Concentrator must first be configured as a device type in ExtremeCloud IQ Controller before it can be used to define a GRE tunneled topology.
Note

Note

In future releases, the IPv4 address will be coupled with IPSEC security options.

Take the following steps to configure a Tunnel Concentrator:

  1. Go to Configure > Devices > Tunnel Concentrators and select Add.
  2. Configure the following parameters:
    Name
    The Tunnel Concentrator name
    Description
    Optional description of the Tunnel Concentrator
    IP Address
    The IPv4 address of the tunnel termination point. Although each AP can support many GRE topologies, a single assigned topology supports three concentrators. IPv6 is not supported.
