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

12 hands-on CCNP Enterprise ENARSI labs covering EIGRP, OSPF, redistribution, route maps, PBR, IP SLA, BGP, MP-BGP, MPLS concepts, VRF-Lite, DMVPN, DHCP, IPv6 first hop security, router hardening, infrastructure services, troubleshooting, and Cisco DNA Center Assurance.

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

CCIE lab notes covering multi-ASN BGP, MPLS, L3VPN, multicast, DMVPN, and service-provider style network design.

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

Cisco Catalyst 8000V on AWS and Azure: SD-WAN, DMVPN, BGP routing, high availability, and cloud-native deployment

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

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.

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
