[Sysname-pim] undo bsm-fragment enable
bsr-policy (PIM view)
Syntax
bsr-policy
acl-number
undo bsr-policy
View
PIM view
Default level
2: System level
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
bsr-policy
to configure a legal BSR address range to guard against BSR spoofing.
Use
undo bsr-policy
to remove the restriction of the BSR address range.
By default, no restrictions are defined for the BSR address range. Namely, the bootstrap messages from
any source are considered eligible.
Examples
# Configure a legal BSR address range so that only devices on the segment 10.1.1.0/24 can become the
BSR.
<Sysname> system-view
[Sysname] acl number 2000
