Configuring H.323 Gatekeepers and Proxies
H.323 Gatekeeper Configuration Examples

Cisco IOS Voice, Video, and Fax Configuration Guide
Gatekeeper gk-sj checks for a technology prefix match but does not find one. It then searches for a zone
prefix match and fails again. But there is a match for default gateway prefix of 4#, and gw-sj4 is
registered with 4#, so the call is routed out on gw-sj4.
Configuring HSRP on the Gatekeeper Example
This sample configuration uses Ethernet 0 as the HSRP interface on both gatekeepers.
On the primary gatekeeper, enter these commands:
configure terminal
! Enter global configuration mode.
interface ethernet 0
! enter interface configuration mode for interface ethernet 0.
standby 1 ip 172.21.127.55
! Member of standby group 1, sharing virtual address 172.21.127.55.
standby 1 preempt
! Claim active role when it has higher priority.
standby 1 timers 5 15
! Hello timer is 5 seconds; hold timer is 15 seconds.
standby 1 priority 110
! Priority is 110.
On the backup gatekeeper, enter these commands:
configure terminal
interface ethernet 0
standby 1 ip 172.21.127.55
standby 1 preempt
standby 1 timers 5 15
The configurations are identical except that gk2 has no standby priority configuration, so it assumes the
default priority of 100—meaning that gk1 has a higher priority.
On both gk1 and gk2, set up identical gatekeeper mode configurations, as follows:
configure terminal
! Enter global configuration mode.
gatekeeper
! Enter gatekeeper configuration mode.
zone local gk-sj cisco.com 172.21.127.55
! Define local zone using HSRP virtual address as gatekeeper RAS address.
.
.
.
! Various other gk-mode configurations.
no shut
! Bring up the gatekeeper.
configure terminal
! Enter global configuration mode.
gatekeeper
! Enter gatekeeper configuration mode.
zone local gk-sj cisco.com 172.21.127.55
! Define local zone using HSRP virtual address as gatekeeper RAS address.
! Note this uses the same gkname and address as on gk1.
.
.
! Various other gk-mode configurations.
no shut
! Bring up the gatekeeper.
