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.
- No packet loss
- Less than a few seconds for a disconnected link to be re-established once it is plugged back in.
Before I go to Bed
Of course, this is a simple test and much more must be tested before deploying. In the following weeks I'll work on this and post some full details, including configuration, but until then, good night!
And oh, the migration job I've been working on; done and done! Migrated and Layer 3 all the way!
