If you send line-rate traffic (via flood) into say 2 x 10GE interfaces, that both need to go out (egress) a single 10GE interface, you have 20GE into 10GE which should provide 50% packet loss, no? I...

Okay, So Relay on SW2 for new users, grabs DHCP Req & points to DHCP Server IP.SW1 which is L3 knows how to route towards DHCP server IP just does IPforwarding then.
