This repository is integration-like work that walks through the process of setting up a BFD (Bidirectional Forwarding Detection) connection between a kind cluster and external containers. The BFD is established using FRR (Free Range Routing).
There are two versions for this setup:
Connection between two nodes and one external docker container - while all on the same network.
Connection between two nodes on one sub-network, and two external containers on different sub-network, and using middle container which functions like a next-hop router.
