CCNAv7 — Enterprise Networking, Security & Automation (ENSA)

🖧 ENSA Network Configuration Project

Cisco Packet Tracer Cisco IOS NETLAB+ George Brown Polytechnic COMP 3136 / COMP 3138

End-of-course Skills Assessment for the CCNAv7 Enterprise Networking, Security, and Automation (ENSA) module. Designed and fully configured a multi-site enterprise network topology in Cisco Packet Tracer, covering dynamic routing, VLAN segmentation, network address translation, access control, and security hardening. The assessment demonstrates readiness for Cisco CCNA certification and industry networking roles.

Topology Description

The network topology spans multiple sites with routers, multilayer switches, and end-point devices connected across WAN and LAN segments. Each site is segmented into department VLANs with a centralised core layer handling inter-VLAN routing. Internet connectivity is simulated via a border router running NAT overload. Security is enforced through standard and extended ACLs applied to relevant interfaces, restricting unauthorised traffic between segments. OSPF area 0 is configured across all routers to enable dynamic route advertisement and convergence.

Technologies Configured

🔀

OSPF Dynamic Routing

Multi-area OSPF configured across all routers for automatic route advertisement and network convergence.

🏷️

VLANs & Trunking

Department VLANs configured on switches with 802.1Q trunk links between access and distribution layers.

🌐

NAT Overload (PAT)

Port Address Translation configured on the border router to enable internet access for all internal hosts.

🛡️

ACL Security Policies

Standard and extended ACLs applied to restrict inter-VLAN and WAN traffic per security policy.

📡

DHCP Services

Centralised DHCP server pools configured to automatically assign IPs to end devices across all VLANs.

✔️

Connectivity Verification

End-to-end connectivity verified using ping, extended ping, traceroute, and Cisco show commands.
