A region is a logical division of the Administrative Domain (AD). Regions consist of network elements that are grouped for geographical or administrative reasons.
VRC recognizes the following region types:
Managed Region - The region and the elements within the region are managed by VRC. A managed region consists of network elements group for geographical or administrative reasons.
A VRC-managed region has one of two role types.
Regular - A managed region is a subset of the VoIP network which is configured by VRC and is defined as a collection of zones, gatekeepers groups, and zero or one associated directory gatekeeper group.
LRQ transit - A special type of managed region which contains only one directory gatekeeper group. This type of region is used for networks with hierarchical DGKs.
Foreign Region - Exists as a peer to all other regions within the AD. It does not contain network elements that are managed by VRC, but it can contain routes that might be terminated on a region's directory gatekeeper group or gatekeeper group.
A region is either meshed or hierarchical.
If the region contains a directory gatekeeper group, it is a hierarchical region.
If the region does not contain a directory gatekeeper group, it is a meshed region.
A typical VRC-managed region might contain:
Directory gatekeeper groups (if it is a hierarchical region)
Gatekeeper groups
Managed zones
Outgoing regional connections
Incoming regional connections
OSP servers
Voice class codecs
To configure authentication between regions, refer to Adding LRQ passwords.
