Ip Address Distribution; Administration And Management; Operational Measurements (Om) - Nortel Meridian 1 Description, Installation And Operation

Gatekeeper Fallover
Both the active leader and backup leader run the Gatekeeper software. When
the backup leader takes over for the active leader upon failure of the active
leader heartbeat, the Gatekeeper on the backup leader takes over for the
Gatekeeper on the active leader.
Clients must re-register with the new gatekeeper in the case of such fallover.

IP Address Distribution

Bootp protocol provides IP address provisioning. The leader card runs a
bootp server, while followers run Bootp clients.
MAT transmits IP address information to the active leader card. The backup
leader card receives its Bootp file from the active leader card.
The backup leader card can detect when the active leader fails. When this
occurs, the backup leader becomes the active leader and takes over its
functions.

Administration and Management

The Gatekeeper requires one file, the Gatekeeper Table file, for management.
This is downloaded via the MAT "ITG M1 IP Lines" application to the card.
The file resides in /C:/TABLE/GKTABLE.1 on the card's file system.
Gatekeeper Table file format
Figure 7 shows the format of the Gatekeeper Table file:
