ACI Multisite using vPC as DCI Transport ,apart around 50 KM

[Ibrahim Jamil]

Hi Freind

is there any configuration Example on how to Connect ACI Multisite using vPC as DCI Transport  , apart around 50  KM from each other , L1 is Darkfiber (over DWDM Circuit) from MOC

thanks

Hi,

Have a look at this post with some examples:

Hi Reza

Thanks for yr reply

what about vPC DCI as a transport?

Hi,

There are a couple of options for DCI like OTV and VPLS. 

Have a look at this white paper:

https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-739609.html

The use case at the bottom of Figure 124 involves converting an existing Multi-Fabric design to a Cisco ACI Multi-Site design. As discussed in the “Layer-3-only connectivity across sites” section, while it is possible to continue to run the ACI fabrics as “autonomous” and establish Layer 3 connectivity only between them through the L3Out data path, there are several advantages when introducing NDO as a single point of management and using the VXLAN data path for east-west connectivity across sites. Additionally, there are several deployments put in production in the past that leveraged an external DCI technology (OTV, VPLS, etc.) for extending Layer 2 connectivity between independent ACI fabrics. This “dual fabric” design is not recommended anymore, so a migration path needs to be provided toward Multi-Site.
