Advanced Gatekeeper Configuration
6-24
5. In the Distance field enter the distance between the Gatekeeper you are defining and
the current Gatekeeper. This value is compared to the Max.Distance or Default
Distance parameters of endpoints to determine whether they can route calls to this
zone. This parameter is optional. Valid values are between 0 and 255.
6. In the Description field enter an identifying description for the neighbor Gatekeeper.
7. Click OK to add this Gatekeeper to the Neighbor Gatekeepers Table.
Editing an Existing Neighbor Gatekeeper
#"
To edit the parameters of an existing neighbor Gatekeeper
1. Select the neighbor Gatekeeper you want to edit and click Edit . The Neighbor GK
Parameters screen is displayed.
2. Make the changes and then click OK to confirm and return to the Neighbor
Gatekeepers Table screen.
Deleting an Existing Neighbor Gatekeeper
#"
To delete an existing Gatekeeper from the Neighbor Gatekeepers Table
•
Select the neighbor Gatekeeper you want to delete and click Delete . The selected
Gatekeeper is deleted from the Neighbor Gatekeepers Table and the current
Gatekeeper will not be able to route calls to endpoints in that zone.
Saving and Loading a File to the Neighbor Gatekeepers Table
You can save the data you define in the Neighbor Gatekeepers Table to a file and load it
when you need it. For details on saving and loading files to the Neighbor Gatekeepers Table
see “Saving the Data of the Zone Definition Table,” page 6-20 and “Loading a Data File to
the Zone Definition Table,” page 6-20. Neighbor Gatekeepers Table data files have an
‘*.nbr’ file extension.
Network Topology
The Network Topology option allows you to define for the Gatekeeper clusters of IP
“subnets” that are characterized by homogenous and fast videoconferencing LAN
connectivity. These IP clusters are called islands. For example, a slow router may connect
two islands. When you define islands, the Gatekeeper can route calls through optimal routes
avoiding slow connections or bottlenecks caused by routers, as much as possible.
You define islands for the Gatekeeper by grouping defined subnets under the same island
code. Each island must consist of at least one subnet. For more information, see
