Configuring a BIDIR-PIM domain border
As the administrative core of a BIDIR-PIM domain, the BSR sends the collected RP-Set information
in the form of bootstrap messages to all routers in the BIDIR-PIM domain.
A BIDIR-PIM domain border is a bootstrap message boundary. Each BSR has its specific service
scope. A number of BIDIR-PIM domain border interfaces partition a network into different BIDIR-PIM
domains. Bootstrap messages cannot cross a domain border in either direction.
Perform the following configuration on routers that you want to configure as the PIM domain border.
To configure a BIDIR-PIM domain border:

By default, no BIDIR-PIM domain
border is configured.
Configuring the global C-BSR parameters
In each BIDIR-PIM domain, a unique BSR is elected from C-BSRs. The C-RPs in the BIDIR-PIM
domain send advertisement messages to the BSR. The BSR summarizes the advertisement
messages to form an RP-set and advertises it to all routers in the BIDIR-PIM domain. All routers use
the same hash algorithm to get the RP address corresponding to specific multicast groups.
The following rules apply to the hash mask length and C-BSR priority:
•
You can configure the hash mask length and C-BSR priority globally, in an admin-scope zone,
and in the global scope zone.
•
The values configured in the global scope zone or admin-scope zone have preference over the
global values.
•
If you do not configure these parameters in the global scope zone or admin-scope zone, the
corresponding global values are used.
For configuration of C-BSR parameters for an admin-scope zone and global scope zone, see
