I’m looking for a guidance setup between my 3 Customers’ VLANs and my building network on nexus7k with VRF leaking .
My main building network:
My main building network VLAN 5 can access to all VLANs and can go to the internet (default route).
CustomerA’s VLAN 10 can access to VLAN 5 and internet but can’t access to VLAN 20 and 30.
CustomerB’s VLAN 20 can’t access to all VLANs but can go to internet.
CustomerC’s VLAN 30 can access to all VLANs but can’t go to the internet.
If OSPF is used in this case, how would I accomplish this? Thanks alot!
