1. Internet Group Management Protocol IGMP is a communications protocol for managing the membership of IP multicast groups IP hosts use IGMP to report multicast group memberships to neighboring multicast routers Multicast routers use IGMP to learn which groups have members on each of the attached networks A multicast router keeps a list of multicast group memberships for each attached network and a timer for each membership Refer to Configuring IP Multicasting page 4 339 for details about IGMP IGMP provides three types of protocol messages used in the host router exchange Query Queries determine group memberships A multicast router sends queries to determine which multicast addresses are of interest to hosts There are two types of queries general and group specific General query A multicast router periodically sends a general query 224 0 0 1 to refresh the group memberships Group specific query A multicast router sends a group specific query for a particular IP multicast address to learn whether a group has any members on an attached network Membership report A host sends a membership report also referred to as a join or report to join a group By sending a report the host expresses interest in receiving packets from a particular multicast group address 76 8800FP801 4 Rev A 1 10 TMOS User Manual IP Multicasting Host Group Multicast Multicast Router 18 Configuring IGMP Snooping e L2. e Multicast Router Expiration Timer page 4 365 e Multicast Router Address page 4 365 Query page 4 366 Query Time Interval page 4 366 e Robustness page 4 366 e Unknown Group page 4 366 The group expiration time parameter group exp timer is the time that a Tellabs 8800 series MSR waits to receive a group membership report before deleting the multicast group address from the multicast forwarding table When the MSR detects a multicast group the MSR adds the group address to the forwarding table and sets the group expiration timer If the MSR does not detect a membership report for that group within the group expiration time the MSR removes the group from the forwarding table The range is 130 65 535 seconds The default is 260 seconds 76 8800FP801 4 Rev A 1 10 TMOS User Manual Immediate Leave Last Member Query Interval Maximum Response Time Multicast Router Address Multicast Router Expiration Timer 76 8800FP801 4 Rev A 1 10 18 Configuring IGMP Snooping The immediate leave or fast leave parameter immediate leave is an IGMPv2 setting that determines whether a Tellabs 8800 series MSR performs host leave processing When enabled the MSR drops the group from the host as soon as a leave report is received the MSR does not perform leave processing With immediate leave disabled the MSR performs leave processing when the MSR receives a leave report from a host You can set immediate leave to
