I found some clues, the best reference was this: http://puck.nether.net/pipermail/juniper-nsp/2005-May/004275.html (though it'd be nice to be able to see how much uKernel heap takes) Some others of interest: http://www.mail-archive.com/juniper-nsp@puck.nether.net/msg01961.html http://www.ip6.atm.tut.fi/list-archive/juniper-nsp-2005/msg00567.html In this case, routing table is taking some 19M, route options (assuming 40B/entry) some 10M, radix trees some 5M, ARP is basically zero. Observing on an empty system, the heap usage is 20% at 11M. 8M is uncached. So, there's still about 9M unaccounted for. (It's also not obvious to me why RPF requires an entry for each routing table entry if you run it in strict mode, smells like a badly implemented feature..) -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
