32 – VXLAN Multipod stretched across geographically dispersed datacenters
This article focuses on the single stretched Fabric across multiple locations as mentioned in the previous post (31) through the 1st option.
I have been working with my friends Patrice and Max for several months building a efficient and resilient solution to stretched a VXLAN Multipod fabric across two sites. The whole technical white paper is now available and can be accessible here:
One of the key use-case for that scenario is for an enterprise to select VXLAN EVPN as the technology of choice for building multiple greenfield data center pods. It becomes therefore logical to extend VXLAN between distant PoD’s that are managed and operated as a single administrative domain. This choice makes sense as a multipod fabric functionally and operationally is a single logical VXLAN fabric, and its deployment is a continuation of the work performed to roll out the pod, simplifying the provisioning of end-to-end Layer 2 and Layer 3 connectivity.
Technically speaking and thanks to the flexibility of VXLAN, we could deploy the overlay network on top of any Layer 3 architecture within a datacenter.
- [Q] However, can we afford to stretch the VXLAN fabric as a single fabric without taking into consideration the risks of loosing the whole resources Continue reading
Cisco also wants everyone to know smaller service providers use ACI, too.
OpenSwitch really is different from Cumulus and Microsoft SONiC.
