communication between same vlan created on two different VDCs

[ccie nithin]

Does the L2 Mac table , ARP communicate between different VDC.

ex:- Vlan 10 created in VDC1 and VDC2

does the L2 communication happen , mac/ARP etc.

how the spanning tree works for vlan10 on VDC1 and VDC2

how the fabric path works for vlan10 on VDC1 and VDC2

Hi,

Creating Vlan 10 on VDC1 and VDC2 means that there is no communication between them untill you allow them to do., 

(Think like this that you have now created Vlan 10 on two different switches. (VDC1 is one switch and VDC2 is another switch).

MAC/ARP/STP/Fabric path are works independent to this now.,

Each VDC is its own switch. They have their own processes, VLANs, routing protocols, spanning-tree, management plane, and configuration. It's really a completely separate switch. Interfaces are assigned to the VDC to provide external connectivity. Inter-VDC communication is only via external interfaces, there is no internal switch like in VMware.

So if you are planning to have inter communication between the three VDCs, then you need to add a link between the different VDC's.

Are you planning to have 1G interfaces of a LC to be a part of different VDCs & these 1G interfaces would be used for inter VDC communication, whereas the external facing interfaces on all these VDCs would be of 10 G capacity.
