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.
