Use the undo multicast ipv6 boundary command to delete a specified IPv6 multicast forwarding boundary or all IPv6 multicast forwarding boundaries.

By default, no multicast forwarding boundary is configured.

Note that:

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

If an interface needs to act as a forwarding boundary for multiple IPv6 multicast groups, just carry out this command on the interface once for each group.

Assume that Set A and Set B are both multicast forwarding boundary sets to be configured, and that B is a subset of A. If A has been configured on an interface, it is not allowed to configure B on the interface; if B has been configured on the interface before A is configured, the previously configured B will be removed.

Parameter limit: Maximum number of downstream nodes (namely the maximum number of outgoing interfaces) for a single route in the IPv6 multicast forwarding table. The value ranges from 0 to 128.

Description Use the multicast ipv6 forwarding-table downstream-limit command to configure the maximum number of downstream nodes for a single route in the IPv6 multicast forwarding table.

Use the undo multicast ipv6 forwarding-table downstream-limit command to restore the system default.

By default, the maximum number of downstream nodes for a single route in the

IPv6 multicast forwarding table is 128.
