  • 1.  Virtual Topology Query from Design Guide

    Posted Sep 07, 2017 07:24 AM

    Hiya,

    I have three queries. I hope they are related and hence I'm using single thread for it.

    Query :01 Below diagram doesn't state exactly between with which DLR and Edge Route peering has to be configured. Is it between Tenant DLR and Tenant NSX Edge? or Tenant DLR and Tier1 NSX Edge?

    Query :02 In Above topology it is clearly stated you cannot have over lapping IP Address If all Tenants are connected to same Edges. But then in "scalable Topology which is extension of Service Provider Topology " it states following  "In addition to increased scalability, this model allows for tenants with overlapping IP addresses to be deployed in separate groups connected to different NSX Edges". Does it suggests that you can have multiple and separate edges for over-lapping IP Address

    Query: 03 This query is on the below topology. In this figure I see all DLR are connected to same Edge with Trunk Interface. It is possible to have over lapping IP Address here?

    Query 1 : Peering is there between Each Tenant DLR all the way to shared ESG (Apart from IP overlapping,One main reason for doing this is for Tenant to Tenant Routing which is not possible between DLR's) . Remember overlapping is only supported on first tier Edge

    Query 2: Since this is a Shared ESG design(Single routing table) ,for a truly multi-tenant topology we need separate L3 ,which can be a ESG or VRF . So ideally each tenant ESG will be connected to dedicated vrf interfaces.

    Query 3: Here each DLR is connected to seperate sub-interface of ESG . The more tenants we have ,we can keep connecting to unique sub-interface(No ip overalapping supported here).

    Thank you Sreec

    Query 3: I was also sure that IP over lapping is not supported. I'm going through Exam Prep video on VCP-NV where it stated it is supported. I was unsure about the authenticity of the answer. Thanks for your time in answering the query
