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

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

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

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

Usage guidelines

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.

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

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.

This configuration does not affect users that come online through an interface configured with IPv6 multicast access control. Such users can still join IPv6 multicast groups specified for the multicast forwarding boundary.

Examples

# Configure HundredGigE 1/0/1 as the forwarding boundary of IPv6 multicast groups in the range of FF03::/16.

<Sysname> system-view

[Sysname] interface hundredgige 1/0/1

[Sysname-HundredGigE1/0/1] ipv6 multicast boundary ff03:: 16

Parameters

per-entry-limit: Specifies the maximum number of unknown IPv6 multicast packets that can be cached for an (S, G) entry. The value range for this argument is 0 to 256. If you set the value to 0, the device cannot cache unknown IPv6 multicast packets.

Parameters

balance-ecmp: Enables IPv6 multicast load balancing based on ECMP paths. Multicast traffic is evenly distributed among ECMP paths.

balance-ucmp: Enables IPv6 multicast load balancing based on links. Multicast traffic is evenly distributed among links.

ecmp: Enables IPv6 multicast load splitting based on ECMP paths.

source: Enables IPv6 multicast load splitting based on IPv6 multicast sources.

source-group: Enables IPv6 multicast load splitting based on IPv6 multicast sources and groups.

ucmp: Enables IPv6 multicast load splitting based on links.

Usage guidelines

On a network with ECMP routes, specify the balance-ecmp, ecmp, source, or source-group keyword. On a network with UCMP routes, specify the balance-ucmp or ucmp keyword.

· If you specify the ecmp keyword, adding or deleting ECMP routes severely affects IPv6 multicast forwarding.

· If you specify the source or source-group keyword, adding or deleting ECMP routes slightly affects IPv6 multicast forwarding. Specify either of the keywords on a network with unstable equal cost links.

· If you specify the balance-ecmp or balance-ucmp keyword, the device uses a polling mechanism for IPv6 multicast load balancing. ECMP or UCMP-based IPv6 multicast load balancing provides better stability and balance than ECMP or UCMP-based IPv6 multicast load sharing.
