Cisco-based advanced network design in GNS3 using VLANs, DHCP, OSPF, VRRP redundancy and failover testing, LACP, RSTP, PortFast, and BPDU Guard. Focuses on reliable Layer 2 and Layer 3 design.

This lab demonstrates the configuration of HSRPv2 on Cisco routers to provide gateway redundancy, ensuring seamless failover between routers in a network. It includes steps to configure HSRP priorities, test failover behavior, and verify connectivity to external servers using a Virtual IP (VIP) as the default gateway.
