source-address: Specifies a multicast source by its IP address.
mask: Subnet mask of the multicast group address or multicast source address, 255.255.255.255 by
default.
mask-length: Subnet mask length of the multicast group address or multicast source address. For a
multicast group address, this argument is in the range of 4 to 32. For a multicast source address, this
argument is in the range of 0 to 32. For both cases, the default value is 32.
Description
Use reset igmp ssm-mapping group to clear multicast group information created based on the
configured IGMP SSM mappings.
If neither all-instance nor vpn-instance is specified, this command clears the information on the public
network.
Related commands: display igmp ssm-mapping group.
Examples
# Clear all multicast group information created based on the configured IGMP SSM mappings on all
interfaces on the public network.
<Sysname> reset igmp ssm-mapping group all
robust-count (IGMP view)
Syntax
robust-count robust-value
undo robust-count
View
Public network IGMP view, VPN instance IGMP view
Default level
2: System level
Parameters
robust-value: IGMP querier's robustness variable, in the range of 2 to 5.
Description
Use robust-count to configure the IGMP querier's robustness variable globally.
Use undo robust-count to restore the default.
By default, the IGMP querier's robustness variable is 2.
The IGMP querier's robustness variable defines the maximum number of attempts for transmitting IGMP
general queries, group-specific queries or group-and-source-specific queries in case of packet loss
because of network problems. A greater value of the robustness variable makes the IGMP querier more
robust, but results in a longer multicast group timeout time.
The IGMP querier's robustness variable determines the following values:
•
The default number of general queries that the IGMPv1/v2/v3 querier sends on startup
The number of IGMP group-specific queries that the IGMPv2 querier sends after receiving an IGMP
•
