Configuring Hsrp on the Gatekeeper Example

Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Examples

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.
