Hi Thanks for the post, that seems like an interesting way to do high-performance forwarding. Is is possible to use this approach when a packet is forwarded between NICs (or at least between multiple ports on one NIC)? So it seems there are at least three ways how to do high-performance forwarding with Linux and BIRD: 1) White-box routers with hardware forwarding plane 2) VPP dataplane 3) tc-based rules that are offloaded to NIC -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) "To err is human -- to blame it on a computer is even more so."
