If the IPv6 multicast address is in the SSM multicast address range, and if an IPv6
address is specified for the multicast source, multicast messages carrying the (S,G)
entry, namely, the source IPv6 address information, can be sent out of this
interface.

Parameter
interval: MLD other querier present interval in seconds, in the range of 60 to 300.
Description
Use the mld timer other-querier-present command to configure the MLD
other querier present interval on the current interface.
other querier present interval on the current interface.
Use the undo mld timer other-querier-present command to restore the
system default.
system default.
By default, the MLD other querier present interval is determined by the following
formula:
formula:
MLD other querier present interval = [ MLD query interval ] times [ MLD querier
robustness variable ] plus [ maximum response delay for MLD general queries ]
divided by two.
robustness variable ] plus [ maximum response delay for MLD general queries ]
divided by two.

By default, the values of the three parameters in the above-mentioned formula are
125, 2, and 10, respectively, so the default MLD other querier present interval is
125 x 2 + 10 / 2 = 255 (seconds).
