bsr-policy (IPv6 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 acl6-number
undo bsr-policy
Default
BSR address range is not defined, and bootstrap messages from any IPv6 multicast sources are regarded
as valid.
Views
IPv6 PIM view
Predefined user roles
network-admin
Parameters
acl6-number: Specifies an IPv6 basic ACL by its number in the range of 2000 to 2999.
Usage guidelines
In an ACL, the source field specifies the source IPv6 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 2001::2/64, so that only the devices
on the subnet 2001::2/64 can act as the BSR.
