For it, I use MPD5.6, Dummynet, Radius, ipfw, quagga. Now I what to using ipv6. For it, I use ipv6cp from MPD and rtadvd from FreeBSD. Rtadvd start and send prefix for each of connect (ngX). Separated conf and rtadvd for each ngX where useing ipv6 (host say yes for ipv6cp). All of this works, but rtadvd make cpu uses to 100%. This is very bad for my server. Why rtadvd do it? I use cpuset for rtadv use only cpu3. Server: Intel SR1630GP, X3470, 4G RAM, Intel 2xigb (576).
