Why is my router sending so many DNS requests for NTP servers?

Your router may try and make a connection to a number of NTP servers and send DNS requests for them. When this happens, CDRouter will send a DNS response with "no such name". Your router may then periodically make other DNS requests for these DNS servers with the same response from CDRouter. Although this is not normally a problem, it can cause issues with the demo version of CDRouter, which has a limitation on how many packets it can send. In this case, you may resolve this problem by configuring either testvar ntpServerName1 or ntpServerName2 with the domain name of one of these servers. This will cause CDRouter to respond to NTP requests from the router under test directly.

For example, if your router attempts to look up an NTP server at ntp.company.com, the following testvar should be updated in your CDRouter configuration file:

   testvar ntpServerName1 ntp.company.com
