Does mikrotik support MPLS/VPLS over GRE? I setup a GRE tunnel between two routers and added the tunnels to LDP and MPLS interfaces. The VPLS tunnels show up as running on both routers with remote and local labels assigned, but I cannot get any traffic to pass over the VPLS tunnels. If I do the same setup using PPTP it works. I'd like to use GRE tunnels as I can encrypt them with IPSEC. If mikrotik does not support VPLS over GRE what about IPIP? I'd rather not use EoIP due to the proprietary nature of the protocol.
