strangebit-io/hip-vpls

HIP-VPLS provides a HIP control plane that establishes authenticated associations between routers, then carries customer LAN traffic across a virtual private LAN. The documented kernel-mode path keeps base exchange and key derivation in Python while Linux bridge/gretap forwarding and XFRM ESP handle customer frames; Python thread/process forwarding remains a fallback. The four router trees appear to be per-router copies, so paths below use router1 as the representative implementation. Unsampled modules are included where the README or source index establishes their role; uncertain internal wiring is omitted.
