Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters. Without this option, the command displays routing information for the public
network.
acl-number: Specifies a basic ACL by its number in the range of 2000 to 2999.

# Define basic ACL 2000 and set the route filtering rules.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 192.168.1.0 0.0.0.255
