Thanks to the NIL Turkey team for the unique network design solution!
We maintain our Internet connectivity through two Service Providers, and we ran BGP as a routing protocol on those links. Generally, when working with two SPs, most engineers make one router active for one SP and another router for the other, configuring BGP between them.
The NIL Turkey team decided on a slightly different approach. They deployed a quite unique VRPP design that allows BGP routers to receive full routing tables and use both links active/active to handle a serious amount of upload traffic. The other benefit of using both lines as active/active state is that each customer can access our services through the closest SP across his/her own SP. This means low latency and high-quality service, which are key factors for brokerage houses.
Even more, the new network design provides that, in case of failover scenarios, even if one of the routers goes down, it takes only 1 ping loss to converge the network again. This solution doesn’t just mean a significantly more bulletproof network design, but also lowers our cost for backup links.
I would like to thank the NIL Turkey team, especially lead engineer Murteza Yilmaz, for a job well done on our network deployment. They completed all the requirements on time and the design works really smoothly, with very fast failovers.
