Ranet3 builds a policy-routed IPsec mesh with IKEv2, Babel and SRv6

ranet3.com 4 min read Editor score 6/10

Ranet3 combines userspace IPsec over UDP, IKEv2 with hybrid ML-KEM key exchange, Babel routing and SRv6 steering. Its use of standard protocols and stated interoperability checks may interest engineers evaluating mesh networking designs.

What

Ranet3 is a policy-routed IPsec mesh SD-WAN using userspace ESP over UDP, IKEv2, Babel and SRv6.

How

Embedded Babel measures link RTT and can route through a relay when the direct path is slower; SRv6 policies steer traffic through chosen waypoints and exits.

Why it matters

Standard protocols let Ranet3 interoperate with compatible routers while running alongside other mesh VPN agents on the same host.
