Displaying the built-in gatekeeper registration list
Cisco TelePresence ISDN Gateway 2.1 Online help (Printable format) 45 of 135
currently have registered. The built-
in gatekeeper will then use the
information received from the
neighbor(s) to reply to the original
request.
Accept
LRQs
Configures the built-in gatekeeper to reply to
LRQs from other gatekeepers.
These requests can come from any
gatekeeper which has the ISDN
Gateway's built-in gatekeeper
configured as one of its neighbors.
Forward
LRQs for
unknown
IDs
Configures the built-in gatekeeper to send (or not
to send) LRQs regarding unknown IDs to its
neighbor(s). Choose from the options:
Disabled: The ISDN Gateway will only
respond to LRQs about IDs registered
with itself. It will not forward LRQs about
IDs that are not registered with itself to
neighboring gatekeepers.
Enabled, using local return address: The
ISDN Gateway will put, in the LRQ, its
own address as the return address for
the LCF.
Enabled, using received return address:
The ISDN Gateway will put, in the LRQ,
the address of the gatekeeper that
originated the request as the return
address for the LCF. Use this option only
if you are configuring the ISDN Gateway
to operate in an environment with a
multiple-level gatekeeper hierarchy. For
example, the 'received address' is
required by the national gatekeepers
connected to the Global Dialing Scheme
(GDS).
Unless you have selected to Accept
LRQs, you cannot configure the
ISDN Gateway to forward any
LRQs.
Enabling using received return
address can be a significant security
risk. Only use this setting with
proper cause.
Accept
LCFs from
non-
neighbors
This setting enables the built-in gatekeeper to
accept LCF message responses from any IP
address.
This setting is for use in
environments with a multiple-level
gatekeeper hierarchy. For example,
this feature is required by the
national gatekeepers connected to
the Global Dialing Scheme (GDS).
Enabling this setting can be a
significant security risk. Only use
this setting with proper cause.
