number of routes with unique inner VPN labels that can be processed by a Juniper
Networks router is increased substantially. Common route update elements associated
with Layer 3 VPNs are combined, reducing the number of route updates and individual
states the Juniper Networks router must maintain, and leading to enhanced scaling and
convergence performance.

You can configure the router based on the number of VPN labels you want to manage
and on whether or not you want to create chained composite next hops for IPv6 labeled
routes:

BEST PRACTICE:
whenever you have deployed Juniper Networks routers in mixed vendor
networks of up to one million routes to support Layer 3 VPNs.
Because using this statement can also enhance the Layer 3 VPN performance
of Juniper Networks routers in networks where only Juniper Networks routers
are deployed, we recommend configuring the statements in these networks
as well.
