L2TPv3 tunnelling and configuration on IAP

Introduction : L2TPv3 tunnelling  is supported form and above 


Feature Notes :


Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs.



The primary requirement is for Aruba IAP to act as LAC(L2TP Access Concentrator) and tunnel all wireless clients L2 traffic from AP to LNS(L2TP Network Server) 


In the context of IAP architecture, this is a centralized L2 model, wherein the VLAN on the corporate side are extended to remote branch sites.  


From the standard perspective L2TPv3 covers the following RFCs:


RFC 3931   -  Layer Two Tunneling Protocol - Version 3 (L2TPv3)


RFC  4719  -  Transport of Ethernet Frames over Layer 2 Tunneling Protocol Version 3 (L2TPv3)


Environment : This feature is only applicable to VC; L2TPv3 supports LNS and VC failover.

Configuration Steps :



Configuring Swarm Name:




l2tpv3 (config) # name aruba1600pop651865.hsbtst2.aus






Configuring L2TPv3 tunnel:




l2tpv3 (config) # l2tpv3 tunnel test


l2tpv3 (L2TPv3 Tunnel Profile "test") # message-digest-type MD5


l2tpv3 (L2TPv3 Tunnel Profile "test") # primary peer-address


l2tpv3 (L2TPv3 Tunnel Profile "test") # secret-key uenmddnjd88dm






L2TPv3 session:




l2tpv3 (config) # l2tpv3 session test_session


l2tpv3 (L2TPv3 Session Profile "test_session") # l2tpv3 tunnel aruba




Note:  Tunnel IP configuration




  • Optional parameter.
  • Needed for the reachability to the AP from corporate side.
  • Example SNMP polling.








l2tpv3 (config) # l2tpv3 session aruba_session


l2tpv3 (L2TPv3 Session Profile "aruba_session") # tunnel-ip mask vlan 10
