Configuring an IPv6 Multicast Boundary

Pre-configuration Tasks

Before configuring IPv6 multicast load splitting, complete the following tasks:

Configure an IPv6 unicast routing protocol to ensure normal unicast routing on the IPv6 network.
Run the multicast ipv6 routing-enable command in the system view to enable Layer 3 IPv6 multicast routing globally.

Context

To restrict forwarding of multicast packets sent to a multicast group within a range on an IPv6 multicast network, configure the IPv6 multicast boundary on interfaces. Then multicast packets sent to the group cannot be forwarded through the boundary interfaces.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
(Optional) On an Ethernet interface, run undo portswitch
The interface is switched to Layer 3 mode.

By default, an Ethernet interface works in Layer 2 mode.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
Run multicast ipv6 boundary { ipv6-group-address ipv6-group-mask-length | scope scope-id }
An IPv6 multicast boundary is configured on the interface.

Verifying the Configuration

After configuring an IPv6 multicast boundary on interfaces, check the IPv6 multicast routing table and information about the multicast boundary on the interfaces to verify that the IPv6 multicast network can operate normally.

Run the display multicast ipv6 routing-table [ ipv6-source-address [ ipv6-source-mask-length ] | ipv6-group-address [ ipv6-group-mask-length ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { { exclude | include | match } { interface-type interface-number | register | none } } ] ^* [ outgoing-interface-number [ number ] ] command to check the IPv6 multicast routing table.
Run the display multicast ipv6 boundary [ ipv6-group-address ipv6-group-mask-length | scope scope-id ] [ interface interface-type interface-number ] command to check information about the IPv6 multicast boundary configured on an interface.
