Multicast Router Ports - Linksys LGS308 User Manual

• Immediate Leave—Select to enable the switch to remove an interface that sends a
leave message from the forwarding table without first sending out MAC-based
general queries to the interface. When an MLD Leave Group message is received
from a host, the system removes the host port from the table entry. After it relays
the MLD queries from the Multicast router, it deletes entries periodically if it does
not receive any MLD membership reports from the Multicast clients. When
enabled, this feature reduces the time it takes to block unnecessary MLD traffic
sent to a device port.
6. Click Apply. The Running Configuration file is updated.

Multicast Router Ports

A Multicast router (Mrouter) port is a port that connects to a Multicast router. The device includes
the Multicast router port(s) numbers when it forwards the Multicast streams and IGMP
registration messages. This is required so that the Multicast routers can, in turn, forward the
Multicast streams and propagate the registration messages to other subnets.
To statically configure or see dynamically-detected ports connected to the Multicast router:
1. Click Configuration > Multicast > Multicast Router Ports.
2. Enter some or all of following query filter criteria:
• VLAN ID—Select the VLAN ID for the router ports that are described
• IP Version--Select IPv4 or IPv6
Interface Type—Select whether to display ports or LAGs.
