Baseline / Minimum Skills

• OSPF multi-area design, LSA types, redistribution (must be able to explain design choices, not just configure)
• BGP eBGP/iBGP, route-reflectors, attributes (AS-path, local-pref, MED), used for DC underlay/WAN edge
• VLAN + Spanning Tree at a design level (STP scaling limitations and why VXLAN replaces it)
• VXLAN/EVPN - overlay concept, VTEPs, MP-BGP EVPN control plane (conceptual + hands-on config)

• Change management ownership - able to write and risk-assess a MOP, not just execute one

Core Responsibilities

• Design and implement DC LAN/WAN changes; own the MOP and rollback plan
• Act as final technical escalation for L2-raised incidents
• Capacity planning and proactive performance/health assessment of the fabric
• Multi-vendor routing coordination for WAN/edge connectivity
