To configure an IPv6 multicast routing policy:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Configure the device to select
the RPF route based on the
longest match.
multicast ipv6 longest-match
Optional.
The route with the highest priority is
selected as the RPF route by
default.
3. Configure IPv6 multicast load
splitting.
multicast ipv6 load-splitting
{source | source-group }
Optional.
Disabled by default.
Configuring an IPv6 multicast forwarding range
IPv6 multicast packets do not travel infinitely in a network. The IPv6 multicast data of each IPv6 multicast
group must be transmitted within a definite scope.
You can configure the forwarding boundary for a specific IPv6 multicast group or an IPv6 multicast group
with the scope field in its group address being specified on all interfaces that support IPv6 multicast
forwarding. A multicast forwarding boundary sets the boundary condition for the IPv6 multicast groups
in the specified range or scope. If the destination address of an IPv6 multicast packet matches the set
boundary condition, the packet will not be forwarded.
Once an IPv6 multicast boundary for an IPv6 multicast group is configured on an interface, this interface
will not receive or forward IPv6 multicast packets of this IPv6 multicast group, or forward locally
generated IPv6 multicast packets.

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type

3. Configure an IPv6 multicast
forwarding boundary.
multicast ipv6 boundary
{ ipv6-group-address prefix-length
| scope { scope-id | admin-local |
global | organization-local |
site-local } }
No forwarding boundary by
default.
Configuring the IPv6 multicast forwarding table size
The router maintains the corresponding forwarding entry for each IPv6 multicast packet that it receives.
Excessive IPv6 multicast routing entries, however, can exhaust the router's memory and cause lower
performance. You can set an upper limit on the number of entries in the IPv6 multicast forwarding table
based on the actual networking situation and the performance requirements. If the configured upper limit
is smaller than the number of existing entries in the IPv6 multicast forwarding table, the entries in excess
are not deleted immediately. The IPv6 multicast routing protocol that runs on the router will delete them.
The router will no longer install new IPv6 multicast forwarding entries until the number of existing IPv6
multicast forwarding entries decreases below the upper limit.
