SDWAN with single MPLS WAN link

How SDWAN router with single MPLS wan link will from control connection with VB,VS & VM as MPLS is peer to peer VPN

Hi @knaik99,

In this case, it is important to understand that when an ISP provides an MPLS transport service, it creates a private network for the customer (VPNv4) or a P2P transport between locations defined by the customer. In the case of VPNv4, the ISP dedicates a VRF to the customer, who will have control over defining the IPs for communication between their points. In the case of P2P transport, it is up to the customer to define the destination points so that they can receive traffic in vManage, vSmart and vBond. In most cases, the customer contracts a transport from a branch directly to their data center.

Hi,

multiple options exists depending on where controllers and how IPs are assigned to controllers (public or private on vNIC) - so where are your controllers located? Do they have public IP on interface or via 1:1NAT?

Generally two options exists

1) advertise /32 controller IPs (can be either private or public) in MPLS cloud so that devices with MPLS TLOC can reach all controllers.

2) MPLS routers interface IP should be NAT/PAT to some IP and reach controllers over internet.

Friend vmanage vbond vsmart is not router it host and it can have IP's in one single subnet.

These three vS vM vB is behind router run mpls' 

The vedge vpn0 connect to this router via mpls' and tunnel run between vedge and vS vM vB is run over this mpls p2p connect.
