Unsolicited Report Interval
– the amount of time in seconds between repetitions of a
par ticular computer’s initial repor t of membership in a group. The default unsolicited
repor t inter val is 10 seconds.
•
Querier Version
– select a version of the IGMP Querier from the pull-down menu:
v1
or
v2
. If you know you will be communicating with other hosts that are limited to v1, for
backward compatibility, select v1; other wise, allow the default v2.
☛
NOTE:
IGMP Querier version is relevant only if the router is configured for IGMP for-
warding. If any IGMP v1 routers are present on the subnet, the querier
must
use IGMP v1. The use of IGMP v1 must be administratively configured, since
there is no reliable way of dynamically determining whether IGMP v1 routers
are present on a network. IGMP for warding is enabled per IP Profile and WAN
Connection Profile.
•
Last Member Query Interval
– the amount of time in tenths of a second that the IGMP
gateway waits to receive a response to a Group-Specific Quer y message. The last mem-
ber quer y inter val is also the amount of time in seconds between successive Group-
Specific Quer y messages. The default last member quer y inter val is 1 second (10 deci-
seconds).
•
Last Member Query Count
– the number of Group-Specific Quer y messages sent
before the gateway assumes that there are no members of the host group being que-
ried on this inter face. The default last member quer y count is 2.
•
Fast Leave
– Checking this checkbox enables a non-standard expedited leave mecha-
nism. The querier keeps track of which client is requesting which channel by IP address.
When a leave message is received, the querier can check its internal table to see if
there are any more clients on this group. If there are none, it immediately sends an
IGMP leave message to the upstream querier. By default, Fast Leave is set to
Off
.
