ME3600X, ME3800X, ASR903 and ASR9K are CE2.0 certified. CE2.0 has two options for L2 control protocol, option 1 and 2. ME3600X supports both the options. ME3600X by default drop all L2 control protocols and one needs to configure "l2protocol xxx" command to enable the transport of control protocol. L2 control protocol has two types of configuration, tunnel and forward. Tunnel is Cisco proprietary and requires tunnel to be supported on the remote device. It is supported with both bridge and Xconnect configuration. Forward on the other hand can interoperate with any switch since it does not change the mac address of control protocols to Cisco well known mac address. It is also supported with both bridge and Xconnect configuration. I would recommend to use "forward" option since CE2.0 options are supported with "forward" configuration only. L2 protocol commands are only allowed on the EVC interfaces. There is no support on Trunk interface. CE2.0 is supported since Release 3.9, March 2013. The behavior on 9K is different. Below is the link with the command and behavior difference details. http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/design/guide/ASR9K_interop_white_paper.pdf

If the customer is directly connected to a PE we normally use 'l2protocol forward'. kind regards Pshem On 30 October 2013 17:15, Jason Lixfeld <ja...@lixfeld.ca<mailto:ja...@lixfeld.ca>> wrote: As far as what I can glean from various configuration guides and other bits of documentation: ME3600s don't support L2 protocol tunneling on cross-connect EVCs, but they do on port based xconnects or on EVCs where the sp-facing interfaces are trunks; they will forward, tunnel or peer various layer 2 protocols. Does that include STP variants (RSTP, PVST, R-PVST, MST, EAPS)? Pause and 802.1x appear to be a part of the MEF CE2.0 spec and it seems the ME3600 is compliant, so I'm presuming these will all work with a port based xconnect? IOS XR configuration docs that I've found seem to say the platform only supports L2 protocol tunnelling for STP, VTP and CDP. Is that it? That seems like a bit of a weak feature set if I'm using something like an A9K as a PE compared to an ME3600. I read a Cisco presentation from July 2013 that says the A9K is MEF CE2.0 compliant so it should support at least everything the ME3600 supports, but I'd expect to be able to find some sort of configuration guide telling me how to configure these L2PT bits. Can anyone point me to some docs?
