Hello everyone,
I've asked to check that I haven't tried as yet.
The scenario is:
A Nexus switch has three VRFs and physical ports are allocated to each VRF.
Can these VRFs be connected to each other via physical cable for route leaking or it is not possible?
I know on VDC it is what Nexus allows.

Hi,
Using physical cable is only for VDC. For VRF, there is no need for cable, you just need to leak them together.

Thanks Reza!
But can we do it or it is allowed in VDC only.

Hi,
If you connect say e1/1 (in vrf1) to e1/2 (in vrf2) using the same switch, you are basically looping physical ports together and can potentially have STP issues.

Hello
Not so sure what you mean here - However fyi -you can have multiple vrfs defined on a switch and also have one physical port with multiple L3 sub-interfaces each within a different vrf and that physical pot connected to another switch via a trunk interface.
Example;
conf t
vrf context Test
vrf context Test1
vrf context Test2
interface Ethernet2/1
no switchport
no shutdown
interface Ethernet2/1.10
encapsulation dot1q 10
vrf member Test
ip address 10.10.10.1/24
interface Ethernet2/1.20
encapsulation dot1q 20
vrf member Test1
ip address 10.20.20.1/24
interface Ethernet2/1.30
encapsulation dot1q 30
vrf member Test2
ip address 10.30.30.1/24

Hi,
Yes, it is possible. You will play with an L3 interface and make multiple subinterfaces. You remote end switch interface will be in trunk mode.
interface Ethernet1/1.9
encapsulation dot1q 9
vrf member VRF-1
ip address <IP ADDR>
interface Ethernet1/1.10
encapsulation dot1q 10
vrf member VRF-2
ip address <IP Addr>
interface Ethernet1/1.11
encapsulation dot1q 11
vrf member VRF-3
ip address <IP Address>
