Parameters
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.
Description
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 all the received
BSR messages are regarded to be valid.
Examples
# Configure a legal BSR address range so that only routers on the segment 10.1.1.0/24
can become the BSR.
