The system view is displayed.
Step 2 Run:

The VPN instance view is displayed.
Step 3 Run:
apply-label per-instance
The MPLS label is allocated based on the VPN instance, which ensures that all the routes in a
VPN instance 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 is introduced and provided by the
S7700. In this manner, all the routes of a VPN instance share the same MPLS label.
