Hello
I'm having trouble understanding what the issue is.
I have 2 different networks, each with 2 pairs of N7K's (each using 2 VDC's) with multiple N5K's connected to all N7K's and both the VDC's.
My set-up works fine for one network but not for the other.
The problem is related to the vPC peer link on fabricpath.
I'm running NX-OS version 6.1(4)
Following is output from my N7K's in the faulty network:
***************************************************************************
N7K11-ione# show vpc
Legend:

Hi Fedric,
Please check below:
For fabricpath isis adjacency to come up, the peer link needs to be a "P2P" interface not a "broadcast" interface.

Hi
Thank you for the input but this isn't the case in my set-up.
The Po's are configured as P2P, see output:
N7K11-ione# show run all | section "interface port-channel1" | grep medium
medium p2p
medium p2p
medium p2p
N7K12-ione# show run all | section "interface port-channel1" | grep medium
medium p2p
medium p2p
medium p2p
(before doing a grep I had a look at the full config...)
Thank you
Frederic

Hello
Before posting my question I had verified almost everything EXCEPT for fabricpath authentication!
Seems that I made a mistake in copy/pasting my config.
The fabric path authentication was missing on my port-channel used for peering.
But thanks for the input!
