Description
RIP (Routing Information Protocol) allows a router to exchange
routing information with other routers. The RIP Direction field
controls the sending and receiving of RIP packets.
Choose Both, In Only or Out Only.
When set to Both or Out Only, the Business Secure Router
broadcasts its routing table periodically.
When set to Both or In Only, the Business Secure Router
incorporates RIP information that it receives.
Select this check box to forward the backup route broadcasts to
the WAN.
Select this check box to turn on IGMP (Internet Group Multicast
Protocol). IGMP is a network layer protocol used to establish
membership in a Multicast group—it is not used to carry user
data.
Select IGMP-v1 or IGMP-v2. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is
still in wide use. For more information about interoperability
between IGMP version 2 and version 1, see sections 4 and 5 of
Internet Group Management Protocol (RFC 2236).
Select this check box to have the dial backup connection on all
of the time.
Select this check box to have the dial backup connection on
during the time that you select.
Type the amount of time (in minutes) that the dial backup
connection can be used during the time configured in the
Period field. Set an amount that is less than the time period
configured in the Period field.
Type the time period (in hours) for how often the budget is
reset. For example, to allow calls to this remote node for a
maximum of 10 minutes every hour, set the Allocated Budget
to 10 (minutes) and the Period to 1 (hour).
Type the number of seconds of idle time (when there is no
traffic from the Business Secure Router to the remote node) for
the Business Secure Router to wait before it automatically
disconnects the dial backup connection. This option applies
only when the Business Secure Router initiates the call. The
dial backup connection never times out if you set this field to 0
(it is the same as selecting Always On).
Specify call schedule sets to use on the dial backup connection.
The call schedule sets must already be configured (see
Chapter 21, "Call scheduling screens," on page 385).
