c-bsr interface-type interface-number [ hash-length [ priority ] ]
The C-BSR is configured.
l interface-type interface-number: specifies the interface where the C-BSR resides. The
l hash-length: specifies the length of the hash. According to the G, C-RP address, and the value

Step 5 (Optional) Run:
bsm semantic fragmentation
The BSR message fragmentation is enabled.
It is recommended to enable BSR message fragmentation on all devices on the network because
BSR message fragmentation can solve the problem faced by IP fragmentation that all fragments
become unavailable due to loss of fragment information.
Step 6 (Optional) Run:
auto-rp listening enable
The Auto-RP listening is enabled.
When the switch interworks with a switch supporting auto-RP, this command needs to be
configured on the switch.

6.3.6 (Optional) Configuring the SSM Group Address Range

The default SSM group address range is 232.0.0.0/8. You can manually configure the SSM group
address range. Ensure that the SSM group address ranges configured on all devices in the network
are identical.
Context
This configuration is optional. By default, the SSM group address range is 232.0.0.0/8.

NOTE
It is recommended to configure the loopback interfaces as RPs.
If the address borrowing is configured, it is not recommended to configure C-RP on the interfaces that
have the same addresses. If the priorities of the interfaces are different, the BSR considers that the C-

In the BSR election, the C-BSR with the highest priority wins. In the case of the same priority,
the C-BSR with the largest IP address wins.
