I'm sitting here in the middle of the night (it's now 06:22) waiting for a provider to do some routing in their network to route some traffic over a satellite link. So I thought I might briefly reflect on a Fabricpath test I did this week with four Cisco Nexus 5596 devices.
As you can see, it's not a full mesh between the Nexus switches. It will be in further tests, but this was a pure functiona test, i.e. does it work and will there be any packet loss if I start pulling cables during a continous ping?
Host A and Host B are in the same subnet connected to Nexus 2248 FEXs. Fabricpath has been configured on all the links interconnecting the Nexus 5596s . The single links between the Nexus 5596s represent a data centre interconnect (DCI) utilising dark fibre (actual distance will be around 10km).
Ping Host B continuously from Host A and unplug any redundant cable.
