Increasing the maximum DNS record size on a Cisco 800 Router

  • 772

Is it possible to increase the maximum record size/cache size supported by the DNS server embedded in a Cisco 800 series router (886VA in my case)? I cannot query large (1500b) TXT records without bypassing Cisco's ip dns server.

  1. Call Cisco and mention to them that it's 2014, and perhaps they should support EDNS0, which has only been around for 10 years now.
