Parameters

ipv6-group-address: Specifies an IPv6 multicast group address in the range of FFxy::/16, where "x" and "y" represent any hexadecimal numbers from 0 to F.

prefix-length: Specifies an address prefix length in the range of 8 to 128.

all: Specifies all IPv6 multicast boundaries configured on the interface.

scope-id: Specifies the ID of an admin-scope zone, in the range of 3 to 15, which is identified by the scope field in the IPv6 multicast group address.

admin-local: Specifies the scope zone as admin-local, which has a scope ID of 4.

global: Specifies the scope zone as global, which has a scope ID of 14.

organization-local: Specifies the scope zone as organization-local, which has a scope ID of 8.

site-local: Specifies the scope zone as site-local, which has a scope ID of 5.

Usage guidelines

You do not need to enable IPv6 multicast routing before executing this command.

A multicast forwarding boundary sets the boundary condition for the IPv6 multicast groups in the specified address range. If the destination address of an IPv6 multicast packet matches the set boundary condition, the packet is not forwarded.

An interface can act as a forwarding boundary for multiple IPv6 multicast groups in different address ranges. You can implement this by using this command on the interface for each multicast address range. These multicast groups must be in the same scope. The latest configuration of a scope overwrites the previous one.

Assume that Set A and Set B are both IPv6 multicast forwarding boundary sets with different address ranges, and that B is a subset of A. A takes effect on the interface no matter whether A is configured earlier or later than B.

Examples

# Configure VLAN-interface 100 to be the forwarding boundary of the IPv6 multicast groups in the range of FF03::/16.

<Sysname> system-view

[Sysname] interface vlan-interface 100

[Sysname-Vlan-interface100] ipv6 multicast boundary ff03:: 16

Parameters

vpn-instance vpn-instance-name: Specifies a VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command clears IPv6 multicast forwarding entries on the public network.

ipv6-source-address: Specifies an IPv6 multicast source address.

ipv6-group-address: Specifies an IPv6 multicast group address in the range of FFxy::/16, where "x" and "y" represent any hexadecimal numbers from 0 to F.

prefix-length: Specifies an address prefix length. The default value is 128. For an IPv6 multicast group address, the value range for this argument is 8 to 128. For an IPv6 multicast source address, the value range for this argument is 0 to 128.

incoming-interface: Specifies the IPv6 multicast forwarding entries that contain the specified incoming interface.

interface-type interface-number: Specifies an incoming interface by its type and number.

all: Specifies all forwarding entries in the IPv6 multicast forwarding entries.

Usage guidelines

When a forwarding entry is deleted from the IPv6 multicast forwarding table, the associated routing entry is also deleted from the IPv6 multicast routing table.

Examples
