fabric path multi-path 009

on DC2
N7K7 & N7K8 will be the spine switches and N7K9 & N7K10 will be
leaf switches.
Ensure that N7K7 is the root for tree1 and N7K9 will be of tree 2.
L2 Multipathing topology and port assignment are displayed in the diagram:

Device            Switch id
N7K7               30
N7K8               40
N7K9               300
N7K10              400

Fabric Path Configuration Part 2 (Practice)
Please refer the diagram:
DC2-N7K3 & DC2-N7K4 , DC2-N5K1 & DC2-N5K-2 enable fabricpath between them.
Port channel between DC2-N7K3 & DC2-N7K4 will not take part on fabricpath.
Create port channel between both Nexus 5K and enable fabricpath on the port
channel .
allow 20 seconds to detect any switch ID conflicts in Fabric path domain.
Make sure that only two equal cost paths are selected in Fabric path doamin.
Make sure DC2-N7K3 & DC2-N7K4 uses DC2-N5K-1 & 2 as equal cost paths.

Device name       switch id
DC2-N7K3           30
DC2-N7K4           40
DC2-N5K-1          50
DC2-N5K-2          60
