MPLS Layer 3 VPN Explained - NetworkLessons.com
Difference between L2 VPN and L3VPN. How EVPN used with L3 MPLS VPN – forwards based on the L3 address of the L3 PDU. The L3 PDU is encapsulated in the transport protocol (MPLS). With MPLS VPN, MP-BGP is used to distribute L3 forwarding information between sites for routes within the VPN. EVPN – Another form of multipoint L2 VPN (LAN type service). Can use MPLS or VXLAN for transport. An ADTRAN White Paper Private IP Service BGP/MPLS VPN … Figure 1. Basic MPLS/BGP VPN Network A Private IP network is architectured around an emerging standard known as RFC 2547 bis or more commonly by BGP/MPLS VPN.Service providers use this approach to combine MPLS for forwarding the data and BGP for controlling the routes in order to construct secure, cost-effective VPNs that are easy to implement. Using OSPF in an MPLS VPN Environment The MPLS VPN routing model introduces a BGP backbone into the customer network. Isolated copies of IGP run at every site and the multi-protocol BGP is used to propagate routes between sites. Redistribution between customer IGP, running between PE-routers and CE-routers and the backbone MP-BGP, is Basic L3VPN (BGP/MPLS VPN or VPRN) configuration on Nokia
RFC 4364 BGP/MPLS IP VPN. I am currently reading RFC 4364 for mpls ip vpn. In there I came across a strange concept about mpls route reflectors. I am under the understanding that route reflectors do not have to run VRF and hence don't need route-targets. The route reflector would be in the VPN core and many times it will not be in the data path
