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.

zone bw gk-eng.xyz.com 2000
