ZXR10(config-mcast-ipv6-mld-if-interface-
name)#
immediate-leave
{

e

Configures the range of
groups allowing MLD leaving
immediately.
By default, when a device
receives an MLD leaving
message, the group member
will leave the group if it
does not receive any report
message within (last member
query interval * 2) seconds. If
no option is configured in the
command, it takes effect in all
multicast groups.
7.
Configure MLD timers.
After MLD is enabled on the interfaces if multicast routers in a shared segment, an
optimal interface will be elected as the querier of the segment to obtain group member
information by sending query messages.
After sending a query message, the querier waits for a period to receive the report
messages from member hosts. The period is the value of the maximum response
time contained in the query messages. By default, the period is 10 seconds.
After receiving the query message, a member host in the segment will subtract a
random value on the basis of the maximum response time. It uses the result as its
response time. If the querier receives a report message from another member host
during this period, the host cancels to send a report message. If the querier does not
receive any report message from any other member hosts when the period expires,
the member host will send a report message. Increasing the maximum response time
also increases the wait chances of group members in the segment, and reduces the
rate that several hosts send report messages in the segment.
Users can set the timers related to the querier according to demand.
To configure MLD timers on the ZXR10 ZSR V2, perform the following steps.
