traffic mirroring/copy (but to a non physical port/bridge)

Hi All

On a RB1100, i have port connected to an upstream provider (Ether9).

I would like to forward all the traffic to a specific VLAN as well as the existing VLAN. (I cant send it to a specific port, because where it needs to go is vm environment).

I’m a bit stumped on how to achieve this, packet sniffer is not scalabe, and the switch port rules dont offer mirroring to anything except physical ports.

I’ve read ways of making a bridge do this, but it involves disabling many features like connection tracking. Surely there is a mangle rule or something that can copy, not just move a packet to another net and send it out?

Regards
