ACI Multipod APIC Initial Setup

Hi Guys,

 

I am setting up a 3 POD Multipod APIC Cluster, the first POD is setup and discovered. The entire cluster has 5 APICs (POD1 - 2 / POD2 - 2 / POD3 - 1, APIC distributions)

 

So for clarity on the 2nd POD APIC -

 

Fabric name - same as the 1st POD APIC?

Fabric ID - same as in 1st POD APIC?

no of Controllers - 5

POD ID - 2

Controller ID - 3

Controler name - APIC-3

TEP IP - 10.230.0.0/16 (POD 1's TEP pool)

Infra VLAN - 3111

GIPO - default

 

Is this accurate and does anyone have a document that details this for Multipod?

 

Thanks,

Tfash

Yes, Multipod is a “single fabric”, as opposed to Multisite.

Thanks for the response, how about the 1st two questions?

 

Fabric name - same as the 1st POD APIC?

Fabric ID - same as in 1st POD APIC?

Hi Nicolas,

Makes a lot of sense, didn't think of it this way. The documentation should be clearer and simpler to read.

Sorry, but I believe this is incorrect. Documentation specifically calls out the use of distinct VTEP Pools per Pod.

Re: ACI Multipod APIC Initial Setup

You're mixing up switches TEP pool and APIC TEP pool.

Switches will have VTEP allocated to POD2 TEP pool, but APIC in POD2 must have its infra TEP address in POD1 TEP.

Read carefully.
