Configuring GSS-TSIG keys You can upload keytab files that contain a single GSS-TSIG key or multiple GSS-TSIG keys on a single NIOS appliance. For each member in the Grid, you can upload up to 256 GSS-TSIG keys in a single keytab file. Trust relationships between AD domains and AD forests are not required.

TSIG key configured on DNS zone You can add a server TSIG key to a DNS zone on the BIG-IP system. With this configuration, the system uses this TSIG key when the zone on the BIG-IP system is a proxy for the zone on the server. Secure Dynamic Zone Update verifies that all RR updates are digitally signed using GSS-TSIG from a domain-joined machine.
You can use these commands to verify your configuration and troubleshoot potential issues. You can also test whether the ap GSS-TSIG updates over all work very well but it is not perfect.
