CHAPTER 2
Configuring IGMP
IP hosts use Internet Group Management Protocol (IGMP) in IPv4 to report their multicast
group memberships to neighboring routers. Similarly, multicast routers, such as an E Series
router, use IGMP to discover which of their hosts belong to multicast groups.
This chapter describes how to configure IGMP for IP multicast on an E Series router; it
