▪ Provided network switch, router, and firewall support in a critical Defence three-star HQ (corporate head office) environment. This included services for three security domains with network traffic segregated by VRF’s at layer 3, using OSPF for routing of onsite prefixes and maintained 60 individual network nodes called the Single Network Infrastructure (SNIF).▪ Designed and implemented enterprise level solutions including site-to-site GRE tunnels over a hub and spoke MPLS circuit… Show more ▪ Provided network switch, router, and firewall support in a critical Defence three-star HQ (corporate head office) environment. This included services for three security domains with network traffic segregated by VRF’s at layer 3, using OSPF for routing of onsite prefixes and maintained 60 individual network nodes called the Single Network Infrastructure (SNIF).▪ Designed and implemented enterprise level solutions including site-to-site GRE tunnels over a hub and spoke MPLS circuit utilising eBGP for routing and DMVPN for encryption and dynamic discovery of tunnel endpoints.▪ Provided enterprise level administration across the headquarters for real-time support to staff completing regular training exercises across the region; regularly on-call and delivered fast-fix solutions to problems.▪ Assisted in engineering a site-wide brownfield switch migration, including configuration of Catalyst 3850’s (IOS-XE), hardening of devices and configuring StackWise to provide network resilience. This also involved decommissioning legacy equipment and documenting new infrastructure.▪ Assessed cyber security bulletins from NATO; performed threat analysis on Common Vulnerabilities and Exposures (CVEs), implemented changes and logged actions.▪ Designed and deployed a lab environment that enabled engineers to create models and what-if scenarios of real-world networks. This gave the department a powerful simulation tool for junior engineers to get hands-on experience in a test environment, then utilising those newly learnt skills into the production network. Furthermore, this created opportunities for more experienced engineers to design, test and troubleshoot complex solutions before pitching them to customers. Show less
