Layer 3 VPN localization

Layer 3 VPN localization provides a mechanism for localizing routes of instance type vrf or virtual-routers to specific Packet Forwarding Engines to help maximize the number of routes or VRFs that a router can handle. To accomplish this, the Layer 3 VPN routes are installed only on the CE-facing Packet Forwarding Engine. By doing this, you can optimize the Packet Forwarding Engine memory. By Layer 3 VPN localization, the number of VPN IP routes that can be handled can be increased by using multiple Layer 3 VPN instances that are distributed across multiple Packet Forwarding Engines.
