Less=20 > moving parts =3D better when you're talking about a router. >=20 To add to that (off-topic); To use flash disks efficiently you=20 really need to look into MFS (Memory File System) as flash disks=20 do not like alot of writing, logs and the like will chew it up if you are unlucky. Flash disks generally do around 1 million writes pr sector=20 before a sector goes bad and the disks integrity is in question.=20 Although for a setup-and-forget system do run tests on the amount=20 of writes/sector of the type of flashdisk because it varies -alot-. Some are cheap and allows only a few hundred thousand, others permit much more. Besides once you have it up and running you can do upgrades by simply ftp'ing a new thoroughly tested MFS file to the router and reboot. This method isnt limited to flash disks either. Going back on to topic, i've successfully used both Zebra and the off-spring Quagga in uptime critical environments with multiple=20 full-table feeds. _// Sten Daniel S=F8rsdal
