IPoE:
- Laptop will broadcast a message asking for DHCP help.
- DHCP will return info that includes IP, subnet mask, and IP address of gateway
- Laptop will ARP to find Mac address correponding to IP address of gateway

Now laptop knows: Its IP, subnet mask, and mac address of gateway
Now it can do some cool stuff.

DHCP uses UDP with L3 broadcast address, using a L2 broadcast frame

The exchange is actually a 4 way handshake (DORA, discovery, offer, request, ack).

Who asked you this question?

Both Discovery and Request are broadcast at L2 and L3 level.
