Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

zone remote gnet-2503-3-gk cisco.com 172.18.194.134 1719

zone prefix gnet-2503-2-gk 919.......

zone prefix gnet-2600-1-gk 919.......

zone prefix gnet-2503-6-gk 919.......

As you can see, the zone prefix for the local gatekeeper (gnet-2503-2-gk) has been inserted at the top of the zone prefix list. If the local gatekeeper can resolve the address, it will not send LRQs to the remote zones.

If you are configuring technology prefixes, the zone prefix for the local gatekeeper should be inserted at the top of the zone prefix list. If the local gatekeeper can resolve the address, it will not send LRQs to the remote zones.

Configuring Local and Remote Gatekeepers

To configure local and remote gatekeepers, 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 local gatekeeper-name

Specifies a zone controlled by a gatekeeper.

 

domain-name [ras-IP-address]

The arguments are as follows:

 

 

 

 

gatekeeper-name—Specifies the gatekeeper name or

 

 

zone name. This is usually the fully

 

 

domain-qualified host name of the gatekeeper. For

 

 

example, if the domain name is cisco.com, the

 

 

gatekeeper name might be gk1.cisco.com. However,

 

 

if the gatekeeper is controlling multiple zones, the

 

 

gatekeeper name for each zone should be some

 

 

unique string that has a mnemonic value.

 

 

domain-name—Specifies the domain name served

 

 

by this gatekeeper.

 

 

ras-IP-address—(Optional) Specifies the IP address

 

 

of one of the interfaces on the gatekeeper. When the

 

 

gatekeeper responds to gatekeeper discovery

 

 

messages, it signals the endpoint or gateway to use

 

 

this address in future communications.

 

 

Note Setting this address for one local zone makes it

 

 

the address used for all local zones.
