Deploying Calico Network Policies on Hardware in Container Cloud Environments

The article answers a technical question about using Calico as the network mode in container cloud networks, explaining that Calico relies on three‑layer routing with BGP, requiring hardware BGP support and sufficient processing capacity to host the full‑mesh routing for all nodes.

Deploying Calico Network Policies on Hardware in Container Cloud Environments

Q1: In a container cloud network, if the Calico network mode is adopted, how should network policies be deployed on the hardware network devices?

A: Calico operates as a three‑layer protocol that replaces virtual switches with virtual routing and propagates information via BGP. Therefore, the underlying data center must enable hardware BGP support. Additionally, Calico requires a dedicated device to store the full‑mesh routing information, so the hardware’s processing capability must exceed the number of nodes to be deployed.
