Why is DHCP snooping required when using the Dynamic ARP Inspection feature?

It relies on the settings of trusted and untrusted ports set by DHCP snooping.

It uses the MAC address table to verify the default gateway IP address.

It redirects ARP requests to the DHCP server for verification.

It uses the MAC-address-to-IP-address binding database to validate an ARP packet.

Refer to the exhibit. Router R1 has an OSPF neighbor relationship with the ISP router over the 192.168.0.32 network. The 192.168.0.36 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/0/1 100 was issued on R1 and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?
