I don't think it's safe to assume "quick" here - at the very least, bgp has a bunch more code handling nexthop validity than ospfd does. Additionally I suspect this will result in bgpd needing to revalidate routes more often, which is a known problem area for out-of-memory crashes in bgpd's RDE. > Adding these two features has obvious and significant benefits.

If running BIRD I'd suggest probably doing it on a Linux-ish system.. While it does get some use on BSDs (I know of someone using it for a big wireless network on FreeBSD) it's originally written for Linux and some things aren't supported on BSDs. Case in point: $ cat `find . -type f` | grep -c RTF_MPATH 0
