Security Against ARP Spoofing

[PRASAD BAIT]

Hi,

I  am planning to create two DHCP servers for DHCP load balancing. Since  ARP Spoofing is one of major threats while configuring DHCP, I want to  know what are the ways to prevent ARP spoofing.

The best is to go with DHCP snooping + Dynamic ARP inspection. This would help against ARP spoofing:
