Chapter 21 Configuring L2TPv3 Over UDP/IP
Mapping SSID to the Tunnel/Xconnect
This interface allows access to an AP through the tunnel. This interface is associated with a VDT
interface with same index. Traffic from this interface is tunneled though a tunnel established with VDT
interface with same index.
Note There will be two default routes leading to a communication failure if the default route from dhcp is not
disabled using the no ip dhcp client request router command.
Examples
ap1# configure terminal
ap1(config)# interface VDT-Mgmt0
ap1(config-subif)# no ip dhcp client request router
ap1(config-subif)# ip address dhcp
ap1(config-subif)# vdt-mgmt vlan 10
ap1(config)# end
Mapping SSID to the Tunnel/Xconnect
Mapping the tunnel to the WLAN is done by adding Xconnect under the ssid configuration.
Beginning in privileged EXEC mode, follow these steps to map the tunnel to the VLAN:
Examples
ap1# configure terminal
ap1(config)# dot11 ssid myssid
ap1(config-ssid)# vlan 10
ap1(config-ssid)# authentication open
ap1(config-ssid)# xconnect 0
ap1(config-ssid)# end
Command Purpose
Step 1
interface VDT-Mgmt index Specifies the VDT management interface.
Step 2
no ip dhcp client request router Disables the default route from dhcp.
Step 3
ip address dhcp | ip netmask Specifies the dhcp IP or static IP.
Step 4
vdt-mgmt vlan 10 Configures the VLAN id.
Command Purpose
Step 1
dot11 ssid ssid Specifies the ssid.
Step 2
vlan vlan id Specifies the VLAN id.
Step 3
xconnect index of VDT interface Enables L2TPv3 for the ssid.
Step 4
authentication open Specifies the type of authentication.
