MLD Proxy Overview
MLD proxy enables the router to issue MLD host messages on behalf of hosts that the
router discovered through standard MLD interfaces. The router acts as a proxy for its
hosts. The E Series router supports MLD proxy versions 1 and 2.
Figure 20 on page 201 shows a router in an MLD proxy configuration. You enable MLD
proxy on one interface, which connects to a router closer to the root of the tree. This
interface is the upstream interface. The attached upstream router on the upstream
interface should be running MLD.
You enable MLD on the interfaces that connect the router to its hosts that are farther
away from the root of the tree. These interfaces are known as downstream interfaces.
