Best Tunnel MTU 1500 FOr PPPOE

HI Dear Friends I used mikrotik and EOIP Tunnel For Layer 2 Connectivitiy And Terminal PPPOE Connection To the PPPO-Server

EOIP Over Head IS very large And my Network layer 3 is congest
DO you Any suggestion That Replace EOIP-Tunnel To Decrease Over head An Router Resouces Usage

Thx

Depending on your network architecture, equipment, etc. the other option is to go OSPF/MPLS with VPLS

Hi My transit Operator Netwok Max mtu on the switch supported 1500 I Cannot used MPLS For USE mtu Transfer switch max mtu 1508

IF used VPLS my mtu routing Must be 1530
Correct ??
