Configuring PIMv6 for IPv6
– 850 –
◆ To use multicast routing, MLD proxy cannot be enabled on any interface
of the device (see "MLD Proxy Routing" on page 1533).
WEB INTERFACE
To enable PIMv6 multicast routing:
1. Click Routing Protocol, PIM6, General.
2. Enable PIM6 Routing Protocol.
3. Click Apply.

protocol’s functional attributes for each interface.

◆ "IPv6 PIM Commands" on page 1950
COMMAND USAGE
◆ Most of the attributes on this page are common to both PIM6-DM and
PIM6-SM. Select Dense or Sparse Mode to display the common
attributes, as well as those applicable to the selected mode.
◆ An IPv6 address must first be assigned to the required routing interface
before PIMv6 can be configured on this page.
◆ PIMv6 and MLD proxy cannot be used at the same time. When an
interface is set to use PIMv6 Dense mode, MLD proxy cannot be
enabled on any interface of the device (see "MLD Proxy Routing" on
page 1533). Also, when MLD proxy is enabled on an interface, PIMv6
cannot be enabled on any interface.
PIM6-DM
◆ PIM6-DM functions similar to DVMRP by periodically flooding the
network with traffic from any active multicast server. It also uses MLD
to determine the presence of multicast group members. The main
difference, is that it uses the router’s unicast routing table to determine
if the interface through which a packet is received provides the shortest
path back to the source.
◆ Dense-mode interfaces are subject to multicast flooding by default, and
are only removed from the multicast routing table when the router
