Parameter: Estimated Groups
Path: Configuration Manager > Protocols > IP > Multicast > IGMP > Global
Default: 20
Options: 5 to 65535 groups
Function: Specifies the estimated number of groups that will be simultaneously active for
this router.
Instructions: Determine the approximate number of groups and enter the value. This allows
the router to utilize memory efficiently. Exceeding this size during router
operation will not cause an error but may cause the router to consume more
memory than required. The following groups are not maintained by IGMP; you
do not need to include them in the count: 224.0.0.1, 224.0.0.4, 224.0.0.5, and
224.0.0.6.
