Data Center Interconnect-a wider two-tier network
This chapter introduces the multi-tier network interconnection technology across data centers, including requirements and business models, highlighting traditional vpls scenarios and emerging OTV scenarios.
Figure Vpls the Network Diagram
The core device is PE, is responsible for the CE access VPLS network
At the same time, end the Vpls tunnel and enter the MPLS+IP core network
Figure OTV the Network Diagram
Through the Otv Gateway, a multi-tier network with control planes is built across the WAN
Diagram Data Center interconnection of several layers
Lisp+otv is the perfect combination.
Lisp separates the identity and location information at the internal communication level, ensuring that the IP of the communication machine is not changed across the data center VLAN
OTV creates a sophomore network reliable link channel outside the data center
NSX is VMware's network virtualization platform for virtual machine image drift and business recovery under fault
