ASR 1001X Vlan setting with etherchannel

I need to connect two separate ASR1001-X to 7010's. I need port channels Layer2 from the ASR's to the 7k's. I am told and as I understand it, "we are talking to a pair of 7k’s on a vdc with no SVI’s". Here is what I have. Can't pass traffic. I have tried multiple different combinations but no success. I do not have access to the 7k's. Any ideas?

Hello.It's completely not

Hello.

It's completely not clear what is configured on Nexuses' side - do you have a template?

Are you using VPC? If so, how are you going to route traffic between Nexuses and the routers (dynamic routing protocols are not supported)?

I assume you need to configure etherchannel as LACP (channel-group xx mode active). Do you see etherchennel is up and running on Nexuses' side?

Why do you need subinterfaces if you have no ip-address on them?

Advisor

You should be putting your IP

You should be putting your IP address on the sub-interface of the Port Channel.

Have you setup one of these ?

I ask because this same question is in LAN  as well and I found a configuration example where they had IPs on both the main port channel interface and the subinterface and I can't for the life of me work out why the main port channel needs IPs and what they are meant to be.
