Technical Skills:

Routing:

• Routing Protocols (BGP routing and SXP peering, EIGRP, RIP and OSPF).
• Route redistribution between IP routing IGPs.
• BGP (Manipulating weight, local preference, MED, as-path, community, Route-reflector).
• Traffic and route Filtering features.
• NAT (static, dynamic and port overloading).
• Gateway redundancy protocols (HSRP, VRRP, and GLBP).
• Configuring policy based routing. Implemented traffic filters using access-lists, Distribute-Lists, and Route Maps.
• Creation of policies as per the requirement of customer.
• Configuration of Multicasting (including media like frame-relay).

Switching:

• Configuration of VLANs to support QoS and private VLANs for enhanced security within VLANs, Etherchannel
• Inter-VLAN routing (SVI and routed ports).
• Layer 2 network attacks (e.g., MAC Flooding, Rogue Devices, VLAN Hopping, DHCP Spoofing).
• Port Security, 802.1x, VACLs, Private VLANs.
• Ether channels (link aggregation).
• Implemented QoS using LLQ,CBWFQ, Priority Queuing, Weighted Round Robin (WRR) ,RSVP, WRED,
• Policing, Shaping, Congestion Management Congestion Avoidance.
