Configuring a BSR Administrative Domain

Configuring a BSR Administrative Domain

By dividing a PIM-SM network into multiple BootStrap router (BSR) administrative domains and a global domain, the workload of a single BSR is reduced and private group addresses can be used for providing special services for users in specific domains.

Context

By default, one PIM-SM domain has only one BSR to manage the entire domain.

To manage networks effectively, configure multiple BSR administrative domains on a PIM-SM network. Each BSR administrative domain maintains only one BSR that serves a multicast group within a specific address range. The multicast group that does not belong to any BSR administrative domain belongs to the global domain. The global domain maintains a BSR that serves the other multicast groups.

NOTE:

You can adjust the hash mask length and priority of the Candidate-BootStrap Router (C-BSR):

  • Global configuration: See Adjusting C-BSR Parameters. The global value takes effect in both the global domain and BSR administrative domains.

  • BSR administrative domain configuration: The configuration for the BSR administrative domain takes precedence over the global configuration. If the configuration for the BSR administrative domain is not available, the global configuration is used.

  • Global domain configuration: The configuration for the global domain takes precedence over the global configuration. If the configuration for the global domain is not available, the global configuration is used.

Procedure

  1. Enable the BSR administrative domain function on all routers.
    1. Run system-view

      The system view is displayed.

    2. Run pim [ vpn-instance vpn-instance-name ]

      The PIM view is displayed.

    3. Run c-bsr admin-scope

      The BSR administrative domain function is enabled.

    4. Run commit

      The configuration is committed.

  2. Set the ranges of multicast groups that Candidate-BootStrap Routers (C-BSRs) in the BSR administrative domain serve and adjust the hash mask lengths and priorities of the C-BSRs in the BSR administrative domain on all C-BSRs.
    1. Run system-view

      The system view is displayed.

    2. Run pim [ vpn-instance vpn-instance-name ]

      The PIM view is displayed.

    3. Run c-bsr group group-address { mask | mask-length } [ hash-length hash-length | priority priority ] *

      The range of the multicast groups that a C-BSR in the BSR administrative domain serves is set, and the hash mask length and priority of the C-BSR in the BSR administrative domain are adjusted.

      group-address { mask | mask-length }: specifies the range of the multicast groups that the C-BSR in the BSR administrative domain serves. The valid multicast groups range from 239.0.0.0 to 239.255.255.255. The ranges of multicast groups that C-BSRs in different BSR administrative domains serve can overlap. The multicast group takes effect only in the local administrative domain, that is, a private multicast group address is used.

    4. Run commit

      The configuration is committed.

  3. (Optional) Adjust the hash mask lengths and priorities of all the C-BSRs in the global domain.
    1. Run system-view

      The system view is displayed.

    2. Run pim [ vpn-instance vpn-instance-name ]

      The PIM view is displayed.

    3. Run c-bsr global [ hash-length hash-length | priority priority ] *

      The hash mask length and priority of a C-BSR in the global domain are adjusted.

    4. Run commit

      The configuration is committed.
