What is a Directory Gatekeeper Group?

A directory gatekeeper group (DGKGrp) is a set of one to five directory gatekeepers (DGKs) configured for redundancy.  

This configuration can be based on a primary, Hot Standby Router Protocol (HSRP), cluster, or overlap directory gatekeepers.

You can add server triggers and zone circuits to a directory gatekeeper group.

Note: You can only add a zone circuit to a directory gatekeeper group if the CSR route type of the AD is set to trunk-label or carrier AND the VRC feature set of the directory gatekeeper group is dp1.1 or later.
