Enabling IPv6 multicast routing
Before you configure any Layer 3 IPv6 multicast functionality, you must enable IPv6 multicast routing.
To enable IPv6 multicast routing:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable IPv6 multicast routing. multicast ipv6 routing-enable Disabled by default.
Configuring IPv6 multicast routing and forwarding
Before you configure IPv6 multicast routing and forwarding, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.
• Configure IPv6 PIM-DM or IPv6 PIM-SM.
• Determine the maximum number of downstream nodes for a single entry in the IPv6 multicast
forwarding table.
• Determine the maximum number of entries in the IPv6 multicast forwarding table.
Configuring an IPv6 multicast routing policy
You can configure the router to determine the RPF route based on the longest match principle. For more
information about RPF route selection, see " RPF check mechanism ."
By configuring per-source or per-source-and-group load splitting, you can optimize the traffic delivery
when multiple IPv6 multicast data streams are handled.
To configure an IPv6 multicast routing policy:
Step 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.
