Views

Parameters
acl-number: Specifies a basic ACL by its number in the range of 2000 to 2999.
Usage guidelines
The source field in an ACL specifies the SSM group range. 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.
You can use this command to define an address range of permitted or denied multicast groups. If a
packet to a multicast group passes the ACL, the multicast mode is PIM-SSM. Otherwise, the multicast
mode is PIM-SM.

# Configure the SSM group range to be 232.1.0.0/16.
