Software-based Border Router

We have looked at using open source routers for our border, but in the end we cannot make the numbers add up. Once Cisco released the x9xx ISR2 routers, the x8xx have tanked in price on the used market. So, for about the same as a vyatta router running on newer hardware that you can trust you can get a 28xx or 38xx. If you also want support, Cisco will support these at less than $100/month and that gets you access to the IOS upgrades and a 4 hr. replacement window. I know I sleep better knowing Cisco will drop off a router in less than 4 hours if one of mine fails.

Subject: Software-based Border Router

Hi All! 

Just want to ask if anyone here had experience deploying software-based routers to serve as perimeter / border router? How does it gauge with hardware-based routers? Any past experiences will be very much appreciated. 

I wanted to know because we've been asked if we want to assume full control of the internet link (up to the router). By assuming control up to the router, we still want to configure iBGP with our parent network so that we can take advantage of some routes available to the parent network's gateway. The saddest part is presently we do not have the router to serve as our gateway this is why we are considering the use of software-based routers. 

Thank you.
