Huawei AR1200 Series Configuration Guide

Step 2 Run:
ip vpn-instance vpn-instance-name
The VPN instance view is displayed.
Step 3 Run:
ipv4-family
The IPv4 address family is enabled for the VPN instance and the VPN instance IPv4 address
family view is displayed.
Step 4 Run:
apply-label per-instance
The MPLS label is allocated based on the VPN instance IPv4 address family, which ensures that
all the routes in a VPN instance IPv4 address family use the same MPLS label.
Generally, MPLS label allocation is in one label per route mode. When the number of routes
becomes larger, more labels are required.
Therefore, MPLS label allocation based on the VPN instance IPv4 address family is introduced
and provided by the AR1200. In this manner, all the routes of a VPN instance share the same
MPLS label.
