Default level
2: System level
Parameters
ipv6-group-address: IPv6 multicast group address, in the range of FFxy::/16, where x and y represent
any hexadecimal number from 0 through F.
prefix-length: Prefix length of an IPv6 multicast group address, in the range of 8 to 128.
scope-id: Specifies the ID of an admin-scope zone in the range 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.
all: Deletes all IPv6 multicast boundaries configured on the interface.
Description
Use multicast ipv6 boundary to configure an IPv6 multicast forwarding boundary.
Use undo multicast ipv6 boundary to delete the specified IPv6 multicast forwarding boundary or all IPv6
multicast forwarding boundaries.
By default, no multicast forwarding boundary is configured.
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 will not be forwarded.
An interface can act as a forwarding boundary for multiple IPv6 multicast groups in different address
ranges. This is implemented by carrying out this command on the interface for each multicast address
range. These multicast groups must in the same scope. The latest configuration of a scope overwrites the
previous one.
Assume that Set A and Set B are both multicast forwarding boundary sets with different address ranges,
and that B is a subset of A. If B is configured after A, A still takes effect. If A is configured after B, B will
be removed.
