In general, each route is assigned a label (one label per route). When a large number of routes
exist, the Incoming Label Map (ILM) needs to maintain a great deal of in-segment entries. This
affects the capacity of the device.
The S9300 can allocate MPLS labels based on VPN instances, that is, allocate a label to each
VPN instance. All the routes in the VPN instance use the same label.
