Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

 

Command

Purpose

 

 

 

Step 3 Router(config-gk)# zone remote

Configures the remote gatekeeper.

 

other-gatekeeper-name other-domain-name

The arguments are as follows:

 

other-gatekeeper-ip-address

 

[port-number]

other-gatekeeper-name—Name of the remote

 

 

 

 

gatekeeper.

 

 

other-domain-name—Domain name of the remote

 

 

gatekeeper.

 

 

other-gatekeeper-ip-address—IP address of the

 

 

remote gatekeeper.

 

 

port-number—(Optional) RAS signaling port

 

 

number for the remote zone. Value ranges from 1 to

 

 

65,535. If this option is not set, the default is the

 

 

well-known RAS port number 1719.

 

 

 

Configuring Redundant Gatekeepers for a Zone Prefix

To configure redundant gatekeepers for a zone prefix, use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# gatekeeper

Enters gatekeeper configuration mode.

Step 2

 

 

Router(config-gk)# zone prefix gatekeeper-name

Adds a prefix to the gatekeeper zone list.

 

e164-prefix[blast seq] [gw-priority priority

For an explanation of the keywords and arguments,

 

gw-alias [gw-alias, ...]]

 

 

see Step 3 of the configuration task table in the

 

 

“Starting a Gatekeeper” section on page 304.

 

 

 

You can configure multiple remote gatekeepers for the same prefix, but only one of the gatekeepers defined for any given zone prefix can be local. It is recommended that you limit the number of remote gatekeepers that service the same zone prefix to two.

By default, LRQs are sent sequentially to the remote gatekeepers. If you would like the LRQs to be sent simultaneously (blast), you need only specify the blast keyword on one zone prefix command per E.164 prefix.

Verifying Zone Prefix Redundancy

To verify the order in which LRQs will be sent to the gatekeepers defined for a zone prefix, enter the show gatekeeper zone prefix command. The following output lists all the gatekeepers, in order, and the zone prefixes serviced by each.

router# show gatekeeper zone prefix
