Usage Guidelines

IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. establishes and manages IP multicast group membership. See RFCRequest For Comments. RFC is a commonly used format for the Internet standards documentss. 3376, “Internet Group Management Protocol, version 3” for more information.

Example

The following command configures IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships.:

(host) [mynode] (config) #ip igmp

(host) ^[mynode] (config-submode)#query-interval 130
