Zebra is about as stable as a trailer park IRC whore who didn't take her meds. It's fine for playing around, and maybe even for a small home PC router where BGP is completely or nearly extraneous, but it is NOT a core router's BGP implementation. :) > But that is basically a problem of the old BSD network stack / crappy > kernel routing (forwarding) table.

Basically just gut the current radix tree and fast-switch like route-cache system, and replace it with something optimized for fast insertions and deletions (and FIB building) but not longest prefix matching for the RIB, and a 4 level 8-bit mtrie (seems to work best for PC hardware) for the FIB. -- Richard A Steenbergen http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
