Configuration Guide IGMP Snooping Configuration
message to the multicast router. In this way, the multicast router will receive multiple IGMP
Report messages when it sends an IGMP Query message to the ports on the IGMP
Snooping-enabled devices.
To reduce the pressure of the server on processing the IGMP Report messages, the switch
only forwards the first received IGMP Report message to the router port while suppressing
other IGMP Report messages. This is called IGMP Snooping Suppression.
To enable IGMP Snooping suppression, execute the following commands in the global
configuration mode:
Ruijie(config)# ip igmp snooping
suppression enable
Enable IGMP Snooping suppression.
By default, this function is enabled.
Ruijie(config)# no ip igmp snooping
suppression enable
Disable IGMP Snooping suppression.
The following example enables the IGMP Snooping suppression function:
Ruijie# configure terminal
Ruijie(config)# ip igmp snooping suppression enalbe
Ruijie(config)# end
Configuring IGMP Profiles
An IGMP Profile entry defines a set of multicast address range and permit/deny activity for the
funcitons like multicast address range for SVGL mode, multicast data range filtered on the
router interface, and IGMP Filtering range. Note that modifying an IGMP Profile after
associating it with a function will influence the multicast forwarding table generated by the
function.
To configure an IGMP profile, execute the following commands:
Ruijie(config)# ip igmp profile
profile-number
Enter the IGMP Profile mode. Assign a number in the range of 1
to 1024 to identify. By default, no profile is configured.
Ruijie (config-profile)# permit |
deny
(Optional) Permit or deny this range of multicast addresses
while deny or permit other multicast addresses. The default
value is deny.
Ruijie(config-profile)# range ip
multicast-address
Add one or more multicast address ranges.
Return to the privileged mode.
To delete an IGMP Profile, use no ip igmp profile profile-number.
To delete a range of the IGMP Profile, use no range ip multicast address.
