PPPoE in vlans

RouterOS Beginner Basics

Hi!
I have pppoe server on my MikroTik, and i need to make it available in the two vlans simultaneously.
I think, there are two ways to make it:

  1. Simply add PPPoE Server on the each VLAN-Interface.
  2. Add vlans into bridge, filter traffic between vlans in the “Bridge Firewall”, and setup PPPoE server on the bridge interface

What would be better, and less cpu-consuming? Thanks.
