Re: Fabric path issue, all of my switches shows metric of 40 or

The 'show fabricpath isis route' command has nothing to do with VLANs. This
command simply shows path & metric information for each FabricPath node in
your network (Learned via IS-IS of course). The numbers you see on the left
column are the SWITCH-ID, not VLAN.

Example:

N7k1# show fabricpath isis route
Fabricpath IS-IS domain: default MT-0
Topology 0, Tree 0, Swid routing table
12, L1
 via port-channel1212, metric 400
111, L1
 via Ethernet3/1, metric 400
1000, L1
 via port-channel1212, metric 400
1001, L1
 via Ethernet3/1, metric 400

In my lab environment, I've manually set the SWITCH-ID and the emulated
(VPC) SWITCH-ID.

The default metric on a 10GE interface is 40, so what you are seeing sounds
correct. You shouldn't ever see IS-IS routes with a metric of 0, with
the 'show fabricpath isis route' command. You can see the metrics on each
of our FabricPath enabled interfaces with: 'show fabricpath isis interface
brief'
