LABEL DESCRIPTION
RIP Direction 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 ZyWALL will broadcast its routing table
periodically.
When set to Both or In Only, the ZyWALL will incorporate RIP information that it
receives.
Broadcast Dial
Backup Route
Select this check box to forward the backup route broadcasts to the WAN.
Enable Multicast 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.
Multicast Version 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. If you would
like to read more detailed information about interoperability between IGMP
version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Budget
Always On Select this check box to have the dial backup connection on all of the time.
Configure Budget Select this check box to have the dial backup connection on during the time that
you select.
Allocated Budget 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.
Period Type the time period (in hours) for how often the budget should be 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).
Idle Timeout Type the number of seconds of idle time (when there is no traffic from the
ZyWALL to the remote node) for the ZyWALL to wait before it automatically
disconnects the dial backup connection. This option applies only when the
ZyWALL 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).
