hello
i have been working with a  huawei ma5608 OLT device and i,m trying to connect an ONT to a BRAS but i,m having trouble understanding how Vlans with stacking atrrib work (how should i remove tags or how to configure bras)
i have configured my OLT according to huawei documents but my OLT terminates the pppoe session pppoe session establishment and does start complete ppp negotiation  (i have tested pppoe by connecting a pc to bras and it worked)
i have added my commands and a pic of error result from  display pppoe simulate  info command
my bras is a mikrotik router and is connected to OLT with a catalyst switch
if you need more info about the network config pls let me know

thank you
