Cisco Systems VC-289 manual Redundant Gatekeepers for a Zone Prefix Example, VC-347

Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Examples

!Preserve our good QoS by not allowing excessive amounts of H.323 traffic

!on the local network. This restricts the traffic within our zone,

!for both intra-zone and interzone calls, to 2 kbps at any given time.

alias static 172.21.127.49 gkid gk-eng.xyz.com terminal h323id joeblow ras 172.21.127.49 1719

!The “user” has an H.323 terminal, which does not support RAS. So we have

!to configure his alias manually so that callers can find him.

Redundant Gatekeepers for a Zone Prefix Example

In the following example, two remote gatekeepers are configured to service the same zone prefix:

gatekeeper

zone remote c2600-1-gk cisco.com 172.18.194.70 1719

zone remote c2514-1-gk cisco.com 172.18.194.71 1719

zone prefix c2600-1-gk 919.......

zone prefix c2514-1-gk 919.......

Redundant Gatekeepers for a Technology Prefix Example

In the following example, two remote gatekeepers are configured to service the same technology prefix:

gatekeeper

zone remote c2600-1-gk cisco.com 172.18.194.70 1719 zone remote c2514-1-gk cisco.com 172.18.194.71 1719 gw-type-prefix 3#* hopoff c2600-1-gk hopoff c2514-1-gk

E.164 Interzone Routing Example

Interzone routing may be configured by using E.164 addresses.

In this example, there are two gatekeepers that need to be able to resolve E.164 addresses. One is in San Jose and the other is in New York. (See Figure 61.)

In sj (San Jose in the 408 area code), the gateways are configured to register with gk-sj as follows:

•gw-sj2 configured to register with technology prefix 2#

•gw-sj3 configured to register with technology prefix 3#

•gw-sj4 configured to register with technology prefix 4#
