[RP-PPPoE] PPPoE relay - forwards unknown MAC address packets

[Ashmath Khan]

Hi,

I am seeing an issue with pppoe relay agent with forwarding packets
having unknown MAC address.
Say I have a device with eth0 and eth1 interface.
eth0 - client side (LAN)
eth1 - server side (WAN)

After PPPoE session is established,
from eth1 send a PPPoE packet with unknown MAC address. Its seen that
the packet gets forwarded onto eth0 and received by the client on LAN
side.

Is there a way PPPoE relay agent can filter these kind of packets with
unknown MAC address ?

thanks
Hashmat
