About your question on # of networks per tenant logical router:
A tenant can have multiple routers.
A specific tenant router can not have more than 9 interfaces.
So a specific tenant router can not be connected to more than 9 networks.
Note: The technical reason is an NSX Edge can not have more than 9 internal interfaces.
Do you have a need a specific tenant logical router connected to more than 9 networks?
And if so, how many?
About your question on "New Shared Edge creation":
A specific NSX Edge can be used by different tenant logical routers.
This limits the # of NSX Edge in the Data Center.
Note: Obviously even if they share the same NSX Edge, FW rules are created so each tenant logical router has no access to other tenant.
When the sum of the different tenant logical router interfaces exceeds 9, then automatically a new Edge is created.
Example:
Step1: Tenant1-LR is created with 3 interfaces
=> Shared-Edge1 with 3 interfaces (used by Tenant1-LR)
Step2: Tenant2-LR is created with 2 interfaces
=> Shared-Edge1 with 5 interfaces (used by Tenant1-LR + Tenant2-LR)
Step1: Tenant3-LR is created with 3 interfaces
=> Shared-Edge1 with 8 interfaces (used by Tenant1-LR + Tenant2-LR + Tenant3-LR)
Step1: Tenant4-LR is created with 2 interfaces
=> Shared-Edge1 with 8 interfaces (used by Tenant1-LR + Tenant2-LR + Tenant3-LR)
=> Shared-Edge2 with 2 interfaces (used by Tenant4-LR)
