# Configuring Multicast Listener Discovery

Hosts use Multicast Listener Discovery (MLD) protocol in IPv6 to report their multicast group memberships to neighboring routers. Similarly, multicast routers, such as the E Series router, use MLD to discover which of their hosts belong to multicast groups.

This chapter describes how to configure MLD on an E Series router; it contains the following sections:
