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
