MX204 tunnel services BW

AIUI, with Trio, you don’t have to disable a physical port, but that comes at the cost of “Tunnel gets whatever bandwidth is left after physical port packets are processed” and likely some additional overhead for managing the sharing.

Could that be what’s happening to you?
