The BV1250 automatically reinitializes its cache based on a user defined
timetable which is setup during Network DNS configuration of BV1250
units. See Section 5.9.1 for configuration procedures.
In addition, information cached in the equipment is routinely verified by
comparing the SOA (Start of Authority) record set in the server and the
version information stored in the BV1250. If the version differs, the cache
is automatically reinitialized. This occurs whenever information in the
server is edited (e.g. a unit is added or deleted).
Configuring Network DNS Facilities
Up to three DNS facilities can be employed in conjunction with a
BV1250 network. These servers are configured in a prioritized fashion.
One server is assigned primary status, and is the first queried during a
call. When additional servers are available, e.g. secondary and tertiary,
each is queried in priority order when the primary server is unavailable. If
all servers are unavailable, a call will be lost.
Multiple DNS servers are assigned as follows:
•
Primary DNS server = 1
•
Secondary DNS server = 2
•
Secondary DNS server = 3
The unit assignment of network DNS addresses and priority access status
is performed during the unit Common Configuration process described in
Section 5.8. Also, a unit's DNS parameters can be individually configured
using the Unit Configuration process described in Section 5.9.1
Up to 2048 office number translation records can be registered with one
external DNS server
Because a unified numbering system is required for a BV1250
network, all servers must employ UNIX BIND Version 4.9.4 or
greater.
