Routing between Sub Interfaces and regular interface

[Anil Verma]

Hi,

I created VLAN sub-interfaces that are routing traffic between sub-interfaces with no problem. However, I am unable to route from a regular L3 interface to the sub-interface. Even an extended ping doesn't work. Here are the details:

- Interface Eth1/1 has two subinterfaces - e1/1.20 (ip 10.10.20.1)  and e1/1.30 (ip 10.10.30.1)

- Int Eth1/4 is a Layer 3 int - ip 10.10.1.1

This setup is on Nexus 7000.

On the router, when I run an extended ping between 10.10.1.1 and 10.10.20.1, it doesn't work.

I can ping all interfaces on the router.

TIA

So just to make sure I understand you are trying an extended ping where the source is one interface and the destination is another, right? It's an odd test that you are trying, but I think it should work.

Can you ping that IP address without specifying the source? What about from other devices besides the N7K, assuming routing is setup correctly.

Can you provide the output to the following commands:

show int brief

show ip int brief

show ip route connected

Hi Anil,

Will you add below command output also:

sh run | b router

Thank you
