Routing Protocols & Design

• Deep understanding of BGP (eBGP/iBGP): path selection, communities, filtering, route-maps, troubleshooting peering issues.
• Proficiency in EIGRP: topology design, summarization, convergence, troubleshooting neighbor relationships and path selection.
• Some experience designing and optimizing hybrid routing environments (internal + external connectivity).
• Ability to assess and refine route redistribution strategies and route filtering for policy enforcement.

Network Design & Architecture

• Experience in designing high-availability architectures: redundancy, failover scenarios, dynamic & (HSRP/VRRP), and resiliency planning.
