The automatic Route Distinguisher (auto RD) feature is designed to simplify customer configuration by automating RD assignment. This feature is supported for the following address families.

This feature extends the BGP Layer 3 VPN Import/Export and VRF Route Leaking functionality to “default” VRF.

BGP VPN routes today advertise a label by dynamically allocating it from a dynamic label range block without providing the user any control over the label value that is allocated per VRF’s address Family - VPNv4 or VPNv6. This feature allows the user to configure a unique label per VRF’s configured address-family, VPNv4 or VPNv6, thereby allowing the user granular control over the label value advertised with VPN routes exported from a VRF.
