Router config examples for MPLS VPN over Multi-point GRE (mGRE) - eiddor/mpls-mgre-configs
"Technically, you can only run MPLS over MPLS if the provider is offering Inter-AS option C or CsC services. What most customers end up doing is running MPLSoGRE where the tunnels are dynamically instantiated under an mGRE interface. The provider MPLS VPN only sees IP packets from the CE which is acting as the enterprise "PE". Next Generation Enterprise MPLS VPN-Based WAN Design and Implementation Guide Chapter 6 WAN Edge—MPLS VPN over DMVPN—2547oDMVPN (Hub and Spoke Only) Platforms Figure 6-1 2547oDMVPN Deployment Platforms Only 7200VXR is supported as the hub router. NPE-G1/G2 is recommended, along with VAM2/VAM2+/VSA modules for encryption. MPLS VPN over mGRE leverages the flexibility that point-to-point MPLS VPN over IP solutions offers, , while simplifying management, configuration, control plane protocols, and overall network operations of any MPLS VPN solution over IP. Because mGRE is a point-to-multipoint model, fully meshed GRE tunnels are not required to interconnect MPLS When a Juniper Networks routing platform receives a VPN route that resolves over a BGP next hop that does not have an MPLS path, a generic routing encapsulation (GRE) tunnel can be created dynamically, allowing the VPN traffic to be forwarded to that route.
Restrictions for MPLS VPN over mGRE • MPLS VPN over mGRE is supported on the Cisco 7600 series routers using the ES-40 line card and the SIP 400 line card as core facing cards. • Tunnelled tag traffic must enter the router through a line card that supports MPLS VPN over mGRE. • Each PE router supports one tunnel configuration only.
There's little contest between ExpressVPN, one of the top 3 services of its kind currently on the market, and HideMyAss, a VPN that might be decent for light applications, but is certainly not Mpls Vpn Over Mgre Configuration secure enough for more sensitive data. Sure, the VPN vs MPLS: Which One to Choose? VPN and MPLS each has its own pros and cons. So you'd better do a cost-benefit analysis to help you decide before deploying VPN or MPLS network. In fact, choosing VPN or MPLS depends on your business requirements, which can come down to such factors as cost, security, availability, QoS, speed , etc.
MPLS VPN is a type of VPN infrastructure that utilizes multiprotocol label switching techniques to deliver its services. It is a suite of different MPLS-based VPN technologies that provide the ability to utilize multiple different protocols and technologies for creating and managing communications in a VPN environment.

May 17, 2015 · MPLS VPN's mGRE This blog post outlines what “MPLS VPNs over mGRE” is all about as well as provide an example of such a configuration. So what is “MPLS VPNs over mGRE”? – Well, basically its taking regular MPLS VPN’s and using it over an IP only core network. Jan 12, 2011 · MPLS/VPN-over-mGRE is the ideal transport solution when you have to deploy any-to-any VPN between sparse PE-routers connected to a core IP-only backbone. Example : your enterprise network has to provide connectivity to a spin-off organization that has its offices located at several sites. When the MPLS VPN over mGRE features is enabled, it allows the operator to deploy a "self deployed" MPLS VPN service on the CE/CPE router connected via the SP service transport offering. This allows one to provision the L3 VPN services without using Label-Switched Path (LSP), Carrier Supporting Carrier (CsC), or a Label Distribution Protocol (LDP). Restrictions for MPLS VPN over mGRE • MPLS VPN over mGRE is supported on the Cisco 7600 series routers using the ES-40 line card and the SIP 400 line card as core facing cards. • Tunnelled tag traffic must enter the router through a line card that supports MPLS VPN over mGRE. • Each PE router supports one tunnel configuration only. The MPLS VPN over mGRE feature also allows you to deploy existing MPLS VPN LSP-encapsulated technology concurrently with MPLS VPN over mGRE and enables the system to determine which encapsulation method is used to route specific traffic. The ingress PE router determines which encapsulation technology to use when a packet is sent to the remote
