The function of BSM semantic fragmentation is enabled by default. A device that does not support this
function might regard a fragment as an entire message and learns only part of the RP-set information.
Therefore, if such devices exist in the IPv6 PIM-SM domain, you need to disable the semantic
fragmentation function on the C-BSRs.
To disable the BSM semantic fragmentation function:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Disable the BSM semantic
fragmentation function.
undo bsm-fragment enable
By default, the BSM semantic
fragmentation function is enabled.
Configuring IPv6 administrative scoping
With IPv6 administrative scoping disabled, an IPv6 PIM-SM domain has only one BSR. The BSR
manages the whole network. To manage your network more effectively and specifically, you can
partition the IPv6 PIM-SM domain into multiple IPv6 admin-scope zones. Each IPv6 admin-scope zone
maintains a BSR, which serves a specific IPv6 multicast group range. The IPv6 global scope zone also
maintains a BSR, which serves the IPv6 multicast groups with the Scope field in the group addresses
being 14.
Enabling IPv6 administrative scoping
Before you configure an IPv6 admin-scope zone, you must enable IPv6 administrative scoping.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
To enable IPv6 administrative scoping:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter IPv6 PIM view.
pim ipv6 N/A
3. Enable IPv6 administrative
scoping.
c-bsr admin-scope Disabled by default.
Configuring an IPv6 admin-scope zone boundary
ZBRs form the boundary of each IPv6 admin-scope zone. Each admin-scope zone maintains a BSR,
which serves multicast groups with a specific Scope field in their group addresses. Multicast protocol
packets (such as assert messages and bootstrap messages) that belong to this range cannot cross the
admin-scope zone boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
