Not sure what the definition of non-trivial is... I have 4 eBGP peers, 2 full views. OSPF inside on 6 routers.

For my ATM gear, I use Cisco. The switches are on 4hr smartnet contract (not cheap). Even so, I doubt if the device failed, I would see a replacement unit in 4hrs, since its a good 2hr drive from the city where they are stored. In the best of circumstances and unless they have ambulance like deployment, I doubt they would be here for a good 6hrs at least. Having a idle replacement unit sitting here is quite expensive... At some point we will be able to justify it, but it does cost a lot. For my border routers, having a cold swap PC sitting around doing nothing ready to be deployed is VERY cheap by comparison.... So it comes down to a calculated risk. Given your network, can you cost justify the Cisco gear ? If yes, then go with the Cisco. If no, go with the PC solution. >It seems to me that a competent Unix sysadmin can gain real control by >using a full Unix machine (well, a carefully secured Unix machine) as a >border router.

BUT, do you need those features for your application ? Also, if your organization is 'gated'ified' or 'zebraized', and you have one person who knows it all, what do you do if he/she leaves ? If you have Cisco gear, you have options in terms of support... You can call up Cisco and buy the solution. For some organizations, this is quite important. Furthermore, you can send people on any number of courses to be trained to operate cisco gear. Again, for some organizations this is important, for others, it does not matter. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Network Administration, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
