Cisco Routing & Switching
Cisco routing and switching platforms provide the foundation for enterprise networks worldwide with industry-leading reliability, security, and advanced features including BGP, OSPF, VLANs, QoS, and software-defined networking.
Overview
Cisco dominates enterprise networking with comprehensive routing and switching portfolios from access switches to core routers and data center fabrics. My extensive experience with Cisco at LionLink Networks and TISTA demonstrates mastery of BGP, OSPF, VLANs, QoS, and advanced networking concepts.
My Cisco Networking Experience
At LionLink Networks, Cisco routing and switching forms the backbone of our multi-data center infrastructure, providing high-performance, reliable connectivity for colocation and hosting clients.
LionLink Network Infrastructure
Built LionLink's network using Cisco Catalyst switches for access and distribution layers, Cisco ASR routers for internet edge with full BGP routing, and Cisco Nexus switches for data center fabrics. Implemented redundant 10GbE and 100GbE uplinks to multiple transit providers, achieving five-nines availability. BGP routing policies optimize traffic paths and provide automatic failover.
BGP and Internet Routing
Established BGP peering with multiple tier-1 transit providers and internet exchanges, maintaining a carrier-grade routing table. Implemented BGP best practices including route filtering, prefix limits, and prefix validation to prevent route leaks. Used BGP communities for traffic engineering with local preference adjustments.
Deployment Scenarios
Cisco routing and switching excels for enterprise campus networks, data center fabrics, service provider networks, multi-site WAN connectivity with MPLS, internet edge routing with BGP multi-homing, and high-security environments requiring compliance.
