Hi Sir, I'm skilled and experiened Network Administrator (only I have TCP/IP passed test). This is because I worked 6 years as Linux/Network Administrator in ISP in Poland. I managed and secured big network to our 7000 customers with tens routers (Cisco, FreeBSD) and switches of different vendors like Cisco, Dlink, TPlink, Allied Telesis, 3Com, Netgear and others. I know every network issues of every level of OSI. And what is the most important thing: I know BGP very very good because in my company I was responsible for that service ,so I configured about 20 peer sessions (iBGP and eBGP) on core router. I decided what traffic and how many of it should go in any direction, I saw many cases. We had 7000 customers, about 3Gb of traffic, about 150 vlans in core, about 300 IPs on core router - and I was responsible for that everything. So, I think I'll be best engineer to that work for you. I'm waiting for you and regards.
