NSX mode ECMP / vCD

[Jauneorange972]

Hello,

NSX mode ECMP is available under sous vCD ?

If yes, how is possible ? I don't see the option when deploying EDGE under vCD, only HA mode.

I mean natively under vCD.

Best regards

Hi Jauneorange972​,

ECMP Edge(s) does not make sense as Tenant Edge in vCD.

What is your usec ase for that?

[paluszekd]

Yes, it's available, but not during the deployment. Must be selected post-deployment and set up. Keep in mind tenant permissions must be established or the provider admin can set it up.

[Jauneorange972]

The main goal is bandwidth.

[Jauneorange972]

So it's possible. I think we need to configure the other step under NSX GUI, nothing possible under vCD GUI,  right ?

Yes, all this does is turns on ECMP for any northbound communication. It assumes you have active/active paths northbound for peering. For example, having provider managed edges that are in ECMP mode.

The Screenshot from paluszekd​ shows the vCD HTML5 UI of an ESG in Advanced Mode.

I would Recommend to have one or more Tenant ESGs in non ECMP mode connected Northbound to an ECMP Cluster of Provider ESGs.

Do you need more bandwith than 10 GBit/s from one OrgVdc Network northbound?

Inner OrgVDC also a DLR is possible southbound to the Tenant ESG.

No, no interface more than 10Gb/s but we were thinking of an option to improve bandwitdh for the nsx edge if we need it.

Thx you all.
