allows the receiver to specify the source or sources it is not interested in receiving the
multicast group traffic from.
For each attached network, a multicast router can be either a querier or a nonquerier. A
querier router, usually one per subnet, solicits group membership information by
transmitting MLD queries. When a host reports to the querier router that it has interested
listeners, the querier router forwards the membership information to the rendezvous
point (RP) router by means of the receiver's (host's) designated router (DR). This builds
the rendezvous-point tree (RPT) connecting the host with interested listeners to the RP
router. The RPT is the initial path used by the sender to transmit information to the
interested listeners. Nonquerier routers do not transmit MLD queries on a subnet but can
do so if the querier router fails.
NOTE: ACX Series routers do not support MLD snooping.
To configure MLD version 1, include the
level as shown below:
[edit protocols]
mld {
interface <interface-name> {
}
}
To configure MLD version 2, include the
level as shown below:
[edit protocols]
mld {
interface <interface-name> {
version 2;
}
}
