Mmm... do you mean IRR data (what bgpq4 generates from RPSL) or RPKI data (what
rpki-client generates from ROAs) ?
As yes, RPKI data we generate into a JSON file and then pass that to a RTR
which serves it up to bird; but IRR data becomes filter statements ("bgpq4 -b"
;) )

Re: Defines for mixed IPv6/IPv4
Hi, I want to also show some example of configuration generation: https://gitlab.com/qratorlabs/example-automatic-filters There are also a couple of links to other similar projects. Jeroen, thanks for the reference to kees, I've added it to the list there too.

Most of the MPLS and EVPN code is protocol independent, but the OS-specific code uses Netlink and assumes Linux. And some implicit assumtions from Linux probably leak also into the OS-independent code. I have no idea how bridging or VXLANs works on BSD. There is the new BSD netlink API, not sure if it covers also this features. -- 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."
