So there is not any real need to use different route-distinguishers within the same customer network, as there tends to be no need for duplicate subnets within the same customer network (this would be a very bespoke design if it did).

Route Distinguisher. Represents a route distinguisher scoped to a route distinguisher group. A route distinguisher is added to the beginning of the customer's IP prefixes to change them into globally unique VPN-IP prefixes. A route distinguisher is made up of two values, the administrative value and the assigned value, which compiled make up

Nov 15, 2016 · A VPN-IPv4 address is a 12-byte quantity, which consists of an 8-byte Route Distinguisher (RD), and a 4-byte IPv4 address. Basically, an IPv4 address can be converted into an VPN-IPv4 address by appending a RD.

(When exchanging the route information by MP-BGP, judgement of which VRF the packet may go to is done by Route Target, but when forwarding packet by MPLS, it is done by VPN ID Label. ) The VPNv4 Prefix is the combination of Route Distinguisher (RD) and the usual prefix [RD: Prefix]. In the case of the figure, and represents a network that is Configuring a VPN Instance on a PE Device - CloudEngine May 08, 2019 Difference between RD and RT - networking-revealed The Route-Distinguisher (RD) & Route-Target (RT) are two different concepts that are both used in an MPLS VPN. The RD is used to keep all prefixes in the BGP table unique, and the RT is used to transfer routes between VRF’s/VPNS. Let’s take a look at an example. In the diagram below, the orange = customer A, and the red = customer B. The MPLS L3 VPN Content - Oracle
