said by cypherstream:Is the best IOS version for the 2811 router 12.4(25g)?
"Depends what you want" would be my answer. There's no exact science to choosing an IOS version and train that I've found.
My other rules of thumb for 12.x IOS is "watch for MD/GD releases for 'stability' (relatively speaking)" and "read the release notes."
