Limiting the Number of IGMP Multicast Group Joins on Logical Interfaces
The group-limit statement enables you to limit the number of IGMP multicast group joins
for logical interfaces. When this statement is enabled on a router running IGMP version 2
(IGMPv2) or version 3 (IGMPv3), the limit is applied upon receipt of the group report.
Once the group limit is reached, subsequent join requests are rejected.
When configuring limits for IGMP multicast groups, keep the following in mind:
•
Each any-source group (*,G) counts as one group toward the limit.
•
Each source-specific group (S,G) counts as one group toward the limit.
•
Groups in IGMPv3 exclude mode are counted toward the limit.
•
Multiple source-specific groups count individually toward the group limit, even if they
are for the same group. For example, (S1, G1) and (S2, G1) would count as two groups
toward the configured limit.
•
Combinations of any-source groups and source-specific groups count individually
toward the group limit, even if they are for the same group. For example, (*, G1) and
(S, G1) would count as two groups toward the configured limit.
•
Configuring and committing a group limit on a network that is lower than what already
exists on the network results in the removal of all groups from the configuration. The
groups must then request to rejoin the network (up to the newly configured group
limit).
•
You can dynamically limit multicast groups on IGMP logical interfaces using dynamic
profiles.
Starting in Junos OS Release 12.2, you can optionally configure a system log warning
threshold for IGMP multicast group joins received on the logical interface. It is helpful to
