Command Mode
Global Configuration
Command Usage
◆ Multicast Router Discovery (MRD) uses multicast router advertisement,
multicast router solicitation, and multicast router termination messages to
discover multicast routers. Devices send solicitation messages in order to solicit
advertisement messages from multicast routers. These messages are used to
discover multicast routers on a directly attached link. Solicitation messages are
also sent whenever a multicast forwarding interface is initialized or re-
initialized. Upon receiving a solicitation on an interface with IP multicast
forwarding and MRD enabled, a router will respond with an advertisement.
◆ Advertisements are sent by routers to advertise that IP multicast forwarding is
enabled. These messages are sent unsolicited periodically on all router
interfaces on which multicast forwarding is enabled. They are sent upon the
expiration of a periodic timer, as a part of a router's start up procedure, during
the restart of a multicast forwarding interface, and on receipt of a solicitation
message. When the multicast services provided to a VLAN is relatively stable,
the use of solicitation messages is not required and may be disabled using the
no ip igmp snooping vlan mrd command.
◆ This command may also be used to disable multicast router solicitation
messages when the upstream router does not support MRD, to reduce the
loading on a busy upstream router, or when IGMP snooping is disabled in a
VLAN.
Example
This example disables sending of multicast router solicitation messages on VLAN 1.
Console(config)#no ip igmp snooping vlan 1 mrd
Console(config)#
ip igmp snooping
vlan proxy-address
This command configures a static source address for locally generated query and
report messages used by IGMP proxy reporting. Use the no form to restore the
default source address.
Syntax
[no] ip igmp snooping vlan vlan-id proxy-address source-address
vlan-id - VLAN ID (Range: 1-4094)
source-address - The source address used for proxied IGMP query and
report, and leave messages. (Any valid IP unicast address)
Default Setting
0.0.0.0
