Hi Adam, L2PT Tunneling as well as L2PT Forward are supported on ME platforms but recommended is L2PT Forward. L2PT tunneling changes the destination mac address to well known Cisco mac address and can only work with remote devices supporting L2PT tunneling. It does not interoperate with non Cisco devices and even has limited support on Cisco devices. L2PT Forward does not change the destination mac address and can interoperate with any Cisco or non Cisco devices. It also supports CE2.0 listed control BPDUs. Due to these reasons, recommendation would be to use L2PT Forward. Below are the documents which has details.

Hi Waris, So on ME3800 I read the l2pt tunnel is not supported on EFPs with PW/xconnect configured on them, though IOS will let you enter the command with no complains. So to work around this I should be using l2pt forward instead right? Is there actually a difference in function of these two commands please? adam -----Original Message----- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Waris Sagheer (waris) Sent: Wednesday, October 02, 2013 6:29 PM To: Chris Russell; cisco-nsp@puck.nether.net<mailto:cisco-nsp@puck.nether.net> Cc: Mostafa Mansour (mosmanso) Subject: Re: [c-nsp] VPLS ASR1k - ME3800 - no L2 tunnelling ? Hi Mostafa, Can you help with ASR1K L2PT behavior? What is supported on ASR1K? Hi Chris, I am copying Mostafa (ASR 1K expert) to confirm the L2PT behavior on ASR1K. Just a side note from ME perspective, I would recommend using L2PT forward command rather than L2PT tunnel.

Is it possible to issue cmd: "l2protocol peer" or all the l2protocol commands are rejected altogether? Just to see if the L2protocol status changes somehow. As a final thread closing to this one, with thanks to various people, especially Adam, who responded - L2 tunnelling of control packets (BPDUs) is NOT supported on the ASR1K.
