Note that Calico by default, routes between nodes within a subnet are distributed using a full node-to-node BGP mesh. Note that Calico by default, routes between nodes within a subnet are distributed using a full node-to-node BGP mesh.
Each node automatically sets up a BGP peering with every other node within the same L2 network. Each node automatically sets up a BGP peering with every other node within the same L2 network.
This full node-to-node mesh per L2 network has its scaling challenges for larger scale deployments. This full node-to-node mesh per L2 network has its scaling challenges for larger scale deployments.
BGP route reflectors can be used as a replacement to a full mesh, and is useful for scaling up a cluster. BGP route reflectors are recommended once the number of nodes goes above ~50-100.
