DNS views are broken in release 12.4(11)T

The Split DNS functionality introduced in IOS release 12.4(9)T has survived a single maintenance cycle before being broken. While you can still configure the DNS views in 12.4(11)T2 (and they still work), the view names are missing from the router-generated configuration (show running, for example), making the configuration syntactically incorrect. The router will thus reboot without DNS views after you've saved the running configuration to NVRAM.

  2. I have them working on my SOHO router in 12.4(15)T1, obviously they've fixed the code in the meantime.
