Additionally, consider implementing three different levels of security for each network, trusted, partially trusted, and non$-$trusted, to address varying security needs.

$2.$ IP Addressing: Assign IP addressing schemes and subnetting strategies to ensure efficient utilization of network resources and facilitate seamless communication.

$3.$ Firewall Implementation: Implement firewall rules and access control policies to secure network traffic and protect against unauthorized access and cyber threats.

$4.$ Routing Protocol Configuration: Configure routing protocols such as DHCP$,$ OSPF or BGP to establish dynamic routing and optimize network traffic flow across office locations.
