As you can see, the zone prefix for the local gatekeeper (gnet-2503-2-gk) has been inserted at the top of
the zone prefix list. If the local gatekeeper can resolve the address, it will not send LRQs to the remote
zones.
If you are configuring technology prefixes, the zone prefix for the local gatekeeper should be inserted at
the top of the zone prefix list. If the local gatekeeper can resolve the address, it will not send LRQs to
the remote zones.
Configuring Local and Remote Gatekeepers
To configure local and remote gatekeepers, use the following commands beginning in global
configuration mode:
Command Purpose
Step 1
Router(config)# gatekeeper
Enters gatekeeper configuration mode.
Step 2
Router(config-gk)# zone local gatekeeper-name
domain-name [ras-IP-address]
Specifies a zone controlled by a gatekeeper.
The arguments are as follows:
• gatekeeper-name—Specifies the gatekeeper name or
zone name. This is usually the fully
domain-qualified host name of the gatekeeper. For
example, if the domain name is cisco.com, the
gatekeeper name might be gk1.cisco.com. However,
if the gatekeeper is controlling multiple zones, the
gatekeeper name for each zone should be some
unique string that has a mnemonic value.
• domain-name—Specifies the domain name served
by this gatekeeper.
• ras-IP-address—(Optional) Specifies the IP address
of one of the interfaces on the gatekeeper. When the
gatekeeper responds to gatekeeper discovery
messages, it signals the endpoint or gateway to use
this address in future communications.
Note Setting this address for one local zone makes it
the address used for all local zones.
