Some time ago I wrote about Huawei Network Simulation Platform eNSP. I have been testing it since it was launched. It is still being developed and new VRP features will be available soon. It looks like it is really useful tool if you want to study Huawei’s datacom technology.
I’ve just found a video guide for eNSP at Huawei’s forum. I hope it will be informative for you.
Anyway, a background music of this guide will have a calming influence on you :)
