ip igmp access-source-group

Syntax

ip igmp access-source-group accessListName

no ip igmp access-source-group

Release Information

Command introduced before JunosE Release 7.1.0.

Description

Restricts hosts on this subnet to membership in those source-groups (also known as “ channels” ) permitted by the specified IP access list. The no version removes any access list restriction.

When this feature is configured, both source and group addresses query the associated access list whenever the router receives an IGMPv3 report requesting membership of the (S,G) pairs (that is, the router receives an IGMPv3 ChangeToInclude, IsInclude, or AllowNewSource group report). The request is rejected if the access list query fails. The ip igmp access-source-group command accepts standard or extended-format access lists. The extended format enables you to specify both the source address and the destination group address; for example, access-list test permit ip host 10.1.1.1 host 224.128.64.32. Typically, you use the extended-format access list. If you instead use the standard-format access list, you explicitly specify the source address to create the access list, but the group address is implicitly assumed to be any, Note that in the access list specified when you issue this command, the source is specified before the group.
