Using BGP at OpenStack to interconnect workloads across clouds

on YouTube ↗39m

" summary

A Python daemon named ovn-bgp-agent runs on every compute node, reads the OVN southbound DB, and programs a per‑node BGP speaker via FRR to advertise VM, load‑balancer and floating IP prefixes (IPv4/IPv6). It creates a dummy interface/VRF and kernel IP rules plus OVS flows to redirect traffic into the OVN overlay; an EVPN mode uses networking‑bgpvpn for tenant isolation. Failover tests show sub‑millisecond convergence; scale testing is still limited and the BGP mode has no API and relies on kernel datapath.
