Caution
By default, no sub-VLAN of the multicast VLAN is configured on the device. By
this time all other VLANs will be able to receive the multicast traffic from master
VLAN.
If sub-VLANs are configured, only VLANs falling into the range of sub-VLANs
can receive multicast traffic.
8.2.15.4 Configuring the Multicast Address
range of Multicast VLAN
After configuring the operating mode of IGMP Snooping to SVGL mode or
IVGL-SVGL mode, you need to associate SVGL to one profile in order to specify
which group addresses can be applied with SVGL mode, namely the member
ports of multicast forwarding table entries can forward traffic across VLAN, while
the member ports of multicast forwarding table entries corresponding to other
multicast address ranges must belong to the same VLAN. By default, no profile is
associated, meaning that no multicast group can be applied with SVGL mode.
Command Function
DES-7200(config)# ip igmp snooping
svgl profile profile_num
Configure to associate one profile with
SVGL.
DES-7200(config)# no ip igmp snooping
svgl profile
Disable SVGL-profile association and
restore to the default value of 0.
The following example shows how to configure the multicast address range
applied with SVGL mode:
DES-7200# configure terminal
DES-7200(config)# ip igmp snooping ivgl-svgl
DES-7200(config)# ip igmp snooping svgl profile 1
DES-7200(config)# end
DES-7200# show ip igmp snooping
