! 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.

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 .)
Figure 61 E.164 Interzone Routing
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#
