BUM traffic flow in ACI
BUM traffic flow in ACI (Single Pod) Below article details the insights on the BUM traffic flow within ACI. The article is based on the assumption that reader is aware of the ACI basic terminology. Cisco ACI as understood uses the hardware VTEP Leaf/Spine architecture. Both Leaf and Spine are allocated the VTEP address assigned dynamically from the pool provided in the APIC configuration. ACI works efficiently in a way to reduce the flooding within the ACI fabric. The bridge domain is defined as the broadcast domain within the ACI architecture. There can exist different EPGs within the same bridge domain. The EPGs within the same bridge domain can be associated with different VLANs. Thus inspite of being in different VLANs the EPGs associated in the same bridge domain are bound to experience flood traffic within the same Bridge domain unlike to the traditional architecture where every VLAN is a different broadcast domain. ACI works on the concept of n...
