Network Engineer

Responsibilities:

• Implementation of several key projects & complex projects. Preparing High Level Design (HLD), Low Level Design (LLD).
• Involved in redesign of Network due to EOL devices include responsibilities to redesign Network for a new connectivity on various sites LAN & WAN and configuring those including creating Visio diagrams.
• Replaced core 6500 switches with Nexus 7K with no single point for failure at 2 Data centers.
• To increase port density associates several Nexus 2K FEX’es for 1G access layer connectivity.
• Was assigned 11 domestic Alabama Clinics, responsibilities were to identify right hardware and configuring them as per standard of infrastructure.
• Worked with service provider for Circuit installation with AT&T and Sprint for Ethernet hand off circuits.
• Technology used during this transition is, BGP, OSPF, Eigrp and with various design best practices as sites are all redundant connected by internet and MPLS circuit of AT&T, SPRINT and Public Internet. Also, used DMVPN to encrypt the traffic based on available bandwidth and circuit type for encrypted redundant connectivity over the internet.
• Hardware used during this transition so far was ASR’s, XR's and 7K, 5K 6800 and 4500X switches. Riverbeds (steel head) are used for load balancing at various sites.
• Developed / fixed route redistribution mechanism between BGP and OSPF for large scale international networks.
• Monitored and troubleshoot EIGRP, MPLS, multi area OSPF and OSPF scale issues.
• Migrated from DMVPN Phase 2 to Phase 3, since Phase 2 is not an optimal solution.
• Ensuring successful implementation utilizing quality methodologies (ITIL)
• Implementing Internet and Branch Office Connectivity, Load Balancing, High Availability and Fault Tolerance for critical business entities. Validating peer reviews to outline client’s requirement and fulfillments.
• Overseeing other project requirements includes writing staged documents and procedure for supporting engineers.
• Writing Procedural document including Operational Guide lines, Turn over to Production, emergency shutdown, WAN disconnections, Health checks etc.
• Document owner ship and availability to customer on request. Designing logical and Fiber layouts of entire campus for customer presentations.
• Internet / WAN Connectivity, Planning, Designing and Implementation of Enterprise Internet Connectivity using
• HSRP /VRRP and BGP for inbound and outbound load balancing and fault-tolerance, with respect to the client’s requirements.
• Working with Capacity management on network bandwidth utilization reporting of the sites WAN link and vendor co-ordination for new site turnovers / WAN links.
