Hi All
I have recently joined this Forum and this is my first post. I have one query related to Layer 2 WAN protocols.
Layer 2 protocols are Ethernet, PPP, Frame relay, ATM however we use PPPoE or PPPoA. I always gets confused because of this that why one layer 2 protocol is able to use another one and what basically PPP do in that case where we have 2 routers running L3 addressing over Ethernet.
Thanks
