The router collects the multicast listener information needed by the multicast routing protocol
and informs itself and other neighboring multicast routers of the listening state.
MLD versions 1 and 2
The purpose of the MLD protocol in the IPv6 multicast architecture is to allow an IPv6 router
to discover the presence of multicast listeners on directly attached links and to discover which
multicast addresses are of interest to neighboring nodes. MLD is the direct IPv6 replacement
for the IGMP protocol used in IPv4. The MLD implementation described in this document is
based on the MLDv2 standard, which is a backward-compatible update to the MLDv1 standard.
QoS and IPv6 filters
Use filtering to block unwanted traffic from entering a switch or to prioritize required traffic.
Filtering is critical to efficient bandwidth management and network protection. You determine
which packets receive special handling based on information in the packet headers.
Traffic filters instruct an interface to selectively handle specified traffic. Using traffic filters, you
can reduce network congestion and control access to network resources by blocking,
forwarding, or prioritizing specified traffic on an interface. You can apply multiple traffic filters
to a single interface.
If you configure IPv6 attributes for an access control template (ACT), you must configure an
access control list (ACL) of type IPv6. If you configure only Ethernet attributes for an ACT, you
can configure two ACLs: one of type IPv4 and one of type IPv6.

License information
The IPv6 feature requires an Advanced License. For more information about licenses, see
Administration, NN46205-605.
IPv6 DHCP Relay
The Dynamic Host Configuration Protocol (DHCP) for IPv6 (RFC 3315) enables DHCP servers
to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. DHCP
