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.


  1. What is the latest release of the IOS that has DNS views working?

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