Configuring a Gatekeeper Example
The following is an annotated example of how to configure a gatekeeper:
hostname gk-eng.xyz.com
! This router serves as the gatekeeper for the engineering community.
! at xyz.com.
ip domain-name xyz.com
! Domain name of this company.
interface Ethernet0
ip address 172.21.127.27 255.255.255.0
! This gatekeeper can be found at address 172.21.127.27.
gatekeeper
! Enter gatekeeper config mode.
zone local gk-eng.xyz.com xyz.com
! Because a zone is, by definition, the area of control of a gatekeeper,
! we tend to use the terms “zone name” and “gatekeeper name” synonymously.
! Here we use the host name as the name of the gatekeeper and zone.
! This is not necessary, but it does simplify administration.
zone remote gk-mfg.xyz.com xyz.com 172.12.10.14 1719
zone remote gk-corp.xyz.com xyz.com 172.12.32.80 1719
! A couple of other zones within xyz.com. We make lots of calls
! between these departments, so we just configure these so we save
! a little time bypassing DNS lookup to find their gatekeepers.
use-proxy gk-eng.xyz.com remote-zone gk-mfg.xyz.com direct
use-proxy gk-eng.xyz.com remote-zone gk-corp.xyz.com direct
use-proxy gk-eng.xyz.com default proxied
! We have good QoS on our local network, so we don't need proxies when
! calling between the xyz.com zones. But for all other zones, we want
! to use proxies.
zone subnet gk-eng.xyz.com 172.21.127.0/24 enable
no zone subnet gk-eng.xyz.com default enable
! We will accept registrations from our local subnet as long as they
! do not specify some other gatekeeper name. We will not accept any
! registrations from any other subnet.
