Flush arp cache

The networking people are replacing routers, building new leads, and placing in new locations.

As for as systems is concern I can just flush the arp cache once there job is done? I will take note of the mac address change of the gateway router. Anything else to check? We have mostly centos.

ip -s -s neigh flush all

copied from the arp man pages

arp -d address will delete a ARP table entry. Root or netadmin priv‐
eledge is required to do this. The entry is found by IP address. If a
hostname is given, it will be resolved before looking up the entry in
the ARP table.

Is that what you're looking for?
