Remote-leaf back-to-back configuration

[Alex17539]

Hello,

I installed a pair of remote-leaf switches, they have 2 back-to-back 100Gb links. On ACI they are visible, but the interface status shows as "out of service" when I check from the CLI. I created the vPC domain, but it doesn’t work.

Eth1/33 and Eth1/34 are the b2b links

What am I missing?

thank you, but b2b of remote-leaf works just with fabric ports and they have LLDP enabled by default.
Indeed lldp is working between them on eth1/33 and eth1/34

Maybe provide more information and configuration output to look at what is wrong?

There’s no configuration to be done, as I said. Once the remote leaves are connected back-to-back, it is supposed to work just like that
