You are configuring IP source guard on a Cisco IOS switch to stop IP spoofing attacks. After you have enabled IP source guard on an interface, the switch blocks all IP traffic received on the interface except specific packets. Which packets are allowed in this situation?routing protocol packetsARP packets allowed by ARP snoopingDHCP packets allowed by DHCP snoopingDNS packets allowed by DNS snooping
