Multipath *does work* on Zerotier on RouterOS and it is enabled by default. It seems to be using balance-aware. Each WAN connection needs a default route and policies to use them with Zerotier. I am using bonded LTE connections on ZT ROS to make this post.

Has anyone been able to get multi-wan working with ZT on ROS? I have 3x WAN links with appropriate routing tables and policy routes for each interface. My other ZT boxes see several paths, but it never seems to aggregate and pulling the active WAN link down causes about five seconds of packet loss. ...

That's cool and all but ROS7 is a non-starter for me without BFD support. Will we ever see BFD implemented is ROS7?

+1, need VTI bad.

+1. Segment Routing and IS-IS would be killer.
