If you do not include this keyword in your command, the correspondingglobal setting will be used.priority: Priority of the C-BSR, in the range of 0 to 255. If you do not include thiskeyword in your command, the corresponding global setting will be used. A largervalue means a higher priority.Description Use the c-bsr command to configure the specified interface a C-BSR.Use the undo c-bsr command to remove the related C-BSR configuration.No C-BSR is configured by default.Related command: pim ipv6 sm, c-bsr hash-length (IPv6 PIM view), c-bsr priority (IPv6 PIMview) and c-rp (IPv6 PIM view).Example # Configure the interface with an IPv6 address of 1101::1 as a C-BSR. system-view[Sysname] pim ipv6[Sysname-pim6] c-bsr 1101::1c-bsr hash-length (IPv6 PIM view)Syntax c-bsr hash-length hash-lengthundo c-bsr hash-lengthView IPv6 PIM viewParameter hash-length: Hash mask length for RP selection calculation, in the range of 0 to128.Description Use the c-bsr hash-length command to configure the global Hash mask lengthfor RP selection calculation.Use the undo c-bsr hash-length command to restore the system default.By default, the Hash mask length for RP selection calculation is 126.Related command: c-bsr (IPv6 PIM view) on page 1461.Example # Set the global Hash mask length for RP selection calculation to 16. system-view[Sysname] pim ipv6[Sysname-pim6] c-bsr hash-length 16
