Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

To verify whether the LRQs will be sent sequentially or simultaneously to the gatekeepers, enter the show running-configcommand. If the LRQs will be sent simultaneously, blast will appear beside the first entry for a particular zone (as shown in the following output for zone 919).

Configuring Redundant Gatekeepers for a Technology Prefix

To configure redundant gatekeepers for a technology 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)# gw-type-prefixtype-prefix

Configures the gatekeepers to service a technology

 

[[hopoff gkid1] [hopoff gkid2] [hopoff gkidn] [seq

zone and specifies whether LRQs should be sent in

 

blast]] [default-technology] [[gw ipaddr ipaddr

blast or sequential fashion. The default is

 

[port]]...]

 

sequential.

 

 

 

 

The keywords and arguments are as follows:

 

 

type-prefix—Specifies that a technology prefix

 

 

is recognized and stripped before checking for

 

 

the zone prefix. It is strongly recommended

 

 

that you select technology prefixes that do not

 

 

lead to ambiguity with zone prefixes. Do this

 

 

by using the # character to terminate

 

 

technology prefixes, for example, 3#.

 

 

hopoff gkid—(Optional) Specifies the

 

 

gatekeeper where the call is to hop off,

 

 

regardless of the zone prefix in the destination

 

 

address. The gkid argument refers to a

 

 

gatekeeper previously configured using the

 

 

zone local or zone remote command. You can

 

 

enter this keyword and argument multiple

 

 

times to configure redundant gatekeepers for a

 

 

given technology prefix.
