Enabling multi cluster connectivity using dynamic routing via BGP in Openstack
The innovative spine leaf architecture is very common in contrast to traditional three tier network architecture in data center network deployments due to lower and predictable latency, improved redundancy and scalability among many other advantages. Openstack plays a critical role in deployment of data centers with spine leaf architecture. The current work is centered on improving the efficiency of BGP routing by introducing fast datapath via offloading the routes using openflow in OVN based deployments with Openstack. A comparative study made in a setup with OVN where BGP advertisement of learnt routes using Free Range Routing (FRR) is done with kernel and openflow routing will be presented. The key takeaway this talk will address is for service providers who have offload capabilities as part of their deployment can leverage the route offload capabilities to accelerate packet processing metric.
