L2TPv3 vs DLSW for Bridging VLANs

I'm currently using DLSW to bridge a VLAN to a remote site and it works fine.  I've been reading up on L2TPv3 and now I'm wondering if one is better than the other for my purposes (my hardware will support both), especially if multiple VLANS are being bridge to the remote site. 

We do not have an MPLS infrastructure, so that's not an option.

Thanks.

Terry, I don't know much about L2TPv3. Dlsw will not participate in  spanning tree, so bridging multiple vlans together could create loops.  Dlsw is process switched, so it will not sustain high traffic loads.  Dlsw is really designed for native Sna or netbios traffic. Matthew

Matt:

Thanks for the info on DLSw using process switching.  I will keep an eye on the CPU usage (so far, so good).

From what I've read since my original post L2TPv3 is a better solution in most cases.  Unfortunately, it can't do point-to-multipoint, which DLSw can.
