Hi Psem, We also did some tests with the ASR901 and we had issues with l2protocol forwarding After some research with cisco, we concluded that
- L2protocol tunnelling is not supported and there is no plan to support it - L2protocol forwarding is supported on EFPs only for untagged PDUs - L2protocol forwarding for tagged PDUs is only supported locally on BD - L2protocol forwarding for both tagged and untagged PDUs is supported with port-based EoMPLS George On Mon, Aug 26, 2013 at 3:24 AM, Pshem Kowalczyk <[email protected]> wrote: > Hi, > > I'm trying to asses if we could use asr901 for our usual metro-E > deployments (where we currently use ME3600x).
