Compatibility
Select
MLD-Auto
,
Forced MLDv1
,
or
Forced MLDv2
. Compatibility is maintained by hosts and
routers taking appropriate actions depending on the versions of MLD operating on hosts and routers
within a network. The default compatibility value is
MLD-Auto
.
MLD-Auto
: Compatibility is automatically assigned.
Forced MLDv1
: Compatibility is forced to MLD version 1. MLD v1 was the original release of MLD as
an asymmetric protocol, specifying different behaviors for multicast listeners and for routers per IETF
Forced MLDv2
: Compatibility is forced to MLD version 2. MLDv2 is designed to be interoperable
with MLDv1. MLDv2 adds the ability for a node to report interest in listening to packets with a
particular multicast address only from specific source addresses or from all sources except for
specific source addresses. Refer to IETF
PRI
Pr
iority of
I
nterface indicates the MLD control frame priority level generated by the system. These
values can be used to prioritize different classes of traffic.
The allowed range is
0
(best effort) to
7
(highest), default interface priority value is 0.
RV
The Robustness Variable allows tuning for the expected packet loss on a link. The valid range is
1
to
255
, default robustness variable value is
2
.
QI
The Query Interval variable - denotes the interval between General Queries sent by the Querier. The
valid range is
1
to
255
seconds. The default query interval is
125
seconds.
QRI (0.1 sec)
Query Response Interval. The Maximum Response Delay used to calculate the Maximum Response
Code inserted into the periodic General Queries. The allowed range is
0
to
31744
in tenths of a
second. The default query response interval is
100
in tenths of a second (10 seconds).
LLQI (0.1 sec)
The Last Listener Query Interval - the Maximum Response Delay used to calculate the Maximum
Response Code inserted into Multicast Address Specific Queries sent in response to Version 1
Multicast Listener Done messages. It is also the Maximum Response Delay used to calculate the
Maximum Response Code inserted into Multicast Address and Source Specific Query messages.
The valid range is
0
to
31744
in tenths of a second. The default last listener query interval is
10
in
tenths of a second (1 second).
URI (sec)
The Unsolicited Report Interval - the time between repetitions of a node's initial report of interest in a
multicast address. The valid range is
0
to
31744
seconds. The default URI is
1
second.
