hsrp

A portable framework for low-level network packet construction

🧨 Generates Cisco scripts based on YAML files

Declare and keep up a rogue default-gateway in Cisco's HSRP default configuration

Cisco enterprise network demonstrating scalable multi-site design with high availability, integrated security, and failover validation

The GNS3-Network-Lab is meant to provide a complete educational experience in Cisco networking.

Hot Standby Router Protocol (HSRP) Set Up With NAT/PAT (Cisco Packet Tracer - For study purpose only)

This is a comprehensive enterprise network lab simulated on GNS3, technologies used: OSPF, HSRP, LACP, Extended ACLs, VTP, SVIs, PAT, DHCP

Multiple CCNA Labs

HSRP (Hot Standby Router Protocol) Topology This lab demonstrates HSRP configuration for gateway redundancy. Two routers (R1 and R2) provide failover for VLAN 10 and VLAN 20 networks. R2 is the active router, while R1 acts as standby. PCs in each VLAN use the virtual gateway for high availability and seamless connectivity to the ISPs.

CCNA Cisco Packet Tracer enterprise network with HSRP, EtherChannel, LACP/PAgP, VTP, VLANs, DHCP, and inter-VLAN routing for high availability.

Network security lab exploring secure remote access architectures, authentication controls and enterprise network protection patterns.

Hot Standby Router Protocol Attack

Enterprise LAN/WAN architecture and security design built with Cisco Packet Tracer. Features OSPF routing, VLAN segmentation, HSRP redundancy, VPNs, and advanced ACL policies.

Layer 3 campus network in GNS3: VLAN segmentation (IT/HR/Guest/DMZ), ACL least-privilege, FortiGate Active–Passive HA with measured ~1s failover and session preservation, HSRP redundancy. Extending to multi-site OSPF + IPsec VPN.

Tool to simplify detection and reporting or network protocols with weak configurations and output into a Nessus like format for import to reporting tools.

Practical CCNA LABs

Comprehensive enterprise network final project featuring OSPF, HSRP, DHCP, EtherChannel, ACLs, NAT, Port Security, Syslog, and NTP. The project demonstrates professional network design, redundancy, security, and monitoring practices.

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.
