bsr-policy (PIM view)
Use bsr-policy to configure the legal bootstrap router (BSR) address range to guard against BSR
spoofing.
Use undo bsr-policy to remove the configuration.
Syntax
bsr-policy acl-number
undo bsr-policy
Default
BSR address range is not defined, and bootstrap messages from any multicast sources are regarded
valid.
Views

Predefined user roles

Parameters
acl-number: Specifies an IPv4 basic ACL by its number in the range of 2000 to 2999.
Usage guidelines
In an ACL, the source field specifies the source address range for the legal BSR. If you specify a VPN
instance in the ACL, the ACL does not take effect. The other optional parameters except the time-range
keyword and the fragment keyword are ignored.
Examples
# On the public network, configure the legal BSR address range to 10.1.1.0/24, so that only the devices
on the subnet 10.1.1.0/24 can act as the BSR.
