acl6-number: Basic IPv6 ACL number, in the range of 2000 to 2999. When an IPv6 ACL is defined, the 

source keyword in the rule command specifies a legal BSR source IPv6 address range. 

Use the bsr-policy command to configure a legal BSR address range to guard against BSR spoofing. 

Use the undo bsr-policy command to remove the restriction of the BSR address range.  

By default, there are no restrictions on the BSR address range, namely the BSR messages from any 

source are regarded to be eligible. 

# Configure a legal BSR address range so that only routers on the segment 2001::2/64 can become the 

BSR.
