About Narendra Kumar Tokala
Network Engineer with 3+ years of hands-on experience in enterprise routing, switching, security, and network automation across Cisco and Juniper environments. Currently at Juniper Networks, I configure and troubleshoot OSPF, BGP, and IS-IS in production networks, manage VLANs, 802.1Q trunking, inter-VLAN routing, and implement IPsec/GRE tunnels for secure WAN connectivity. I perform firewall policy reviews on Palo Alto and Check Point devices, handle ACL/NAT changes, and analyze traffic using Wireshark and NetFlow to resolve latency and routing issues within SLA timelines. I also develop Python automation scripts using Netmiko and Paramiko for bulk configuration pushes, device compliance validation, and operational efficiency improvements. Previously at Cybage Software, I supported multi-site enterprise networks with OSPF/EIGRP routing, STP optimization, VLAN segmentation, DHCP Snooping, and Dynamic ARP Inspection. CCNA certified, with a Master’s from Purdue University Northwest, focused on scalable network design, automation, and performance optimization.

Jan 2025 — Present · St Louis, MO, US
In my current role as a Network Engineer, I work on configuring and managing enterprise routing protocols such as OSPF, BGP, and IS-IS across Juniper and Cisco platforms. I handle VLAN provisioning, inter-VLAN routing, trunk configurations, and both Layer 2 and Layer 3 troubleshooting in production environments. I configure and maintain IPsec and GRE tunnels to support secure site-to-site connectivity. My responsibilities also include firewall policy reviews and updates on Palo Alto and Check Point devices, along with ACL and NAT rule modifications. I actively participate in change management processes using ServiceNow, ensuring proper validation and rollback planning for all changes. For troubleshooting, I use tools like Wireshark and NetFlow to analyze traffic patterns and resolve performance issues within SLA timelines. Additionally, I develop Python automation scripts using Netmiko and Paramiko to perform bulk configuration updates and compliance checks across multiple devices.
