DMVPN Phase 3 Practical Lab – Transport Company Scenario

Learning guide for DMVPN and ZBFW-based network security on Microsoft Azure

Cisco CML lab simulating an African SP NOC with MPLS L3VPN, BGP, VRF, DIA and SD-WAN — 15 IOSv devices

This project demonstrates a Dynamic Multipoint VPN (DMVPN) enterprise network implemented in PNETLab. The topology connects multiple branch sites to a central Hub through an ISP core, providing scalable, secure, and dynamic site-to-site connectivity. The lab combines DMVPN Phase architecture, IPsec security, and dynamic routing

GNS3 network labs covering BGP, OSPF, EIGRP, DMVPN, HSRP, GLBP, and Ansible automation on Cisco IOS routers

ENARSI-focused routing lab covering OSPF, BGP, DMVPN, redistribution, failover testing, troubleshooting, and incident runbooks.

DMVPN Phase 3 with IKEv2 IPsec, OSPF point-to-multipoint and NHRP shortcuts. Covers DPD, OSPF authentication, IP SLA tunnel monitoring and Phase 2 vs Phase 3 comparison. Topology: 1 Hub + 4 Spokes | Tools: GNS3/PNetLab

TCL script that runs on a Cisco IOS device to automate the backup of a Certificate Authority.

Fully automated deployment and validation of a scalable DMVPN Phase 3 network (Dual Hub, IKEv2, BGP). Built with Ansible to solve real-world legacy cryptography interoperability challenges.

DMVPN Phase 2 hub-and-spoke design with EIGRP and IPsec. Covers NHRP configuration, spoke-to-spoke direct tunnels, route filtering and redundancy testing. Topology: 1 Hub + 3 Spokes | Tools: GNS3/PNetLab

This lab depicts an MPLS network running OSPF as the IGP that services 2 customer networks. One customer network is running DMVPN with IPSEC over eBGP, the other is running DMVPN with IPSEC over a BGP confederation. Still a work in progress.
