To verify whether the LRQs will be sent sequentially or simultaneously to the gatekeepers, enter the
show running-config command. If the LRQs will be sent simultaneously, blast will appear beside the
first entry for a particular zone (as shown in the following output for zone 919).

Configuring Redundant Gatekeepers for a Technology Prefix
To configure redundant gatekeepers for a technology prefix, 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)# gw-type-prefix type-prefix
[[hopoff gkid1] [hopoff gkid2] [hopoff gkidn] [seq |
blast]] [default-technology] [[gw ipaddr ipaddr
[port]]...]
Configures the gatekeepers to service a technology
zone and specifies whether LRQs should be sent in
blast or sequential fashion. The default is
sequential.
The keywords and arguments are as follows:
• type-prefix—Specifies that a technology prefix
is recognized and stripped before checking for
the zone prefix. It is strongly recommended
that you select technology prefixes that do not
lead to ambiguity with zone prefixes. Do this
by using the # character to terminate
technology prefixes, for example, 3#.
• hopoff gkid—(Optional) Specifies the
gatekeeper where the call is to hop off,
regardless of the zone prefix in the destination
address. The gkid argument refers to a
gatekeeper previously configured using the
zone local or zone remote command. You can
enter this keyword and argument multiple
times to configure redundant gatekeepers for a
given technology prefix.
