The c-bsr group command specifies the range of multicast groups that an administrative domain can serve on a C-BSR.
The undo c-bsr group command restores the default configuration.
By default, range of multicast groups that an administrative domain can serve is not configured.
c-bsr group group-address { mask | mask-length } [ hash-length hash-length | priority priority ] *
undo c-bsr group group-address
| Parameter | Description | Value |
|---|---|---|
| group-address | Specifies a multicast group address. | The address is in dotted decimal notation. The value ranges from 239.0.0.0 to 239.255.255.255. |
| mask | Specifies the mask of a multicast group address. | The address is in dotted decimal notation. |
| mask-length | Indicates the mask length of a multicast address. | The value is an integer ranging from 8 to 32. |
| hash-length hash-length | Specifies the hash mask length for the C-BSR in a BSR administrative domain. | The value is an integer ranging from 0 to 32. By default, it is 30. |
| priority priority | Specifies the priority of the C-BSR in the BSR administrative domain. A larger value indicates a higher priority. | The value is an integer ranging from 0 to 255. By default, it is 0. |
Usage Scenario
After a PIM-SM domain is divided into different BSR administrative domains, configure a multicast group address for each BSR administrative domain on the C-BSR. The group addresses must be in the range of 239.0.0.0/8. The group address ranges served by different BSR administrative domains can overlap. The address of a multicast group that a BSR administrative domain serves is used as a private group address.
By running this command on the C-BSR of each administrative domain, you can specify the group address of the administrative domain served by each C-BSR and the priority of each C-BSR.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command in the public network instance or VPN instance.
Configuration Impact
If the c-bsr group command is run several times, the latest configuration overrides the previous one.
After the undo pim command or the undo multicast routing-enable command is run in the system view or the VPN instance view, the C-BSRs in the BSR administrative domain are automatically disabled.
