NSX routing design decisions
Assume that we have already decided what routing protocol is required for a particular use case. Design factors are key in ensuring that they work flawlessly:
If we are a service provider, and multi tenancy is required for DLR control VM and Edge Services Gateway (ESG), we should deploy a separate instance, which would ease the management. We can also achieve true isolation between the tenants.
Area Border Router (ABR) should be a physical router.
If we are not leveraging the High Availability (HA) feature for ESG and DLR, ensure that tenant ESG and DLR VM are not residing on the same ESXi host. However, recommended practice would be to leverage HA for DLR control VM and ESG with vSphere HA.
If there is a shortage of interfaces in ESG, we should leverage the trunk interface so that multiple DLR can be connected to the same ESG.
DLR to DLR peering is not possible.
IPsec with dynamic routing is not supported.
Use route summarization wherever we can.
