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

keyword in the rule command specifies a legal BSR source 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 bootstrap messages from 

any source are regarded to be valid.  

# Configure a legal BSR address range in the public instance so that only routers on the segment 

10.1.1.0/24 can become the BSR.
