Will there be any load-sharing between multiple IPN links ?

Hello Experts ,

If we have multi pod topology and we have 2 or more links connecting the IPN devices then how the traffic flows ...Will the link act as Active/Standby or will there be load-sharing ?

We have below schema , from this what I understand is , we have 40Gig of bandwidth on the link which connects 2 Pod's .Am I right ?

The load will be shared across both IPN links - assuming both Spines have the same uplink bandwidth to each IPN switch.  Routes will be learned from each Spine <>IPN path, beyond that its just standard OSPF L3 hashing taking effect.

so what will be total bandwidth between POD1 and POD2 ? Can we say its 80Gig ?

Hi @Network_Sarovani 

You can refer to this answer. Hector has explained traffic flow through IPNs.
