Adding or leaving a multicast domain

Syntax: 


[no] igmp-proxy-domain domain-name [border-router-ip-address | mcast-range | all]

The no form of the command is used to remove a multicast domain.

All VLANs associated with the domain must first be removed for this command to work. See the no form of igmp-proxy in the VLAN context command.

domain-name

User-defined name to associate with the PIM border router and multicast range that is being sent toward the border router.

border-router-ip-addr

The IP address of the border router toward which IGMP proxy packets are sent. Not required for the no form of the command.

NOTE:

The current routing FIB determines the best path toward the border router and therefore the VLAN that a proxy is sent out on

[low-bound-ip-address | all]

The low boundary (inclusive) of the multicast address range to associate with this domain (for example, 234.0.0.1.)

If all is selected, the multicast addresses in the range of 224.0.1.0 to 239.255.255.255 are included in this domain.

NOTE:

Addresses 224.0.0.0 to 224.0.0.255 are never used, because these addresses are reserved for protocols.

high-bound-ip-address

The high boundary (inclusive) of the multicast address range to associate with this domain (for example, 236.1.1.1.)

IGMP proxy border IP address command

This example shows the IGMP proxy border IP addresses (111.11.111.111) being configured.

switch(config)# igmp-proxy-domain Bob 111.11.111.111

Setting the lower and upper bounds for multicasting

This example shows the lower and upper boundaries of the multicast address range associated with the domain named Bob.

switch(config)# igmp-proxy-domain Bob 111.11.111.111 234.0.0.1
switch(config)# igmp-proxy-domain Bob 111.11.111.111 236.1.1.1
