# Configuring MLD and MLD Proxy

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 and MLD proxy on an E Series router; it contains the following sections:

- MLD Overview
- MLD Platform Considerations
- MLD References
- Static and Dynamic MLD Interfaces
- Enabling MLD on an Interface
- Configuring MLD Settings on an Interface
- Configuring Multicast Groups for MLD
- MLD SSM Mapping Overview
- Overview of Limiting the Number of Accepted MLD Groups
- MLD Traffic Overview
- MLD Explicit Host Tracking Overview
- Configuring MLD Attributes
- MLD Proxy Overview
- Configuring MLD Proxy
- Establishing the MLD Proxy Baseline
