Thanks for your help guys.
Information you posted is very useful, but does not solve my problem.
I need to compare router models between Cisco and Huawei.
For example: I have Cisco ISR 2921, what shouldbe the equivalent model with Huawei ARG3 routers?
I remember there was a presentation that compares Cisco vs Huawei routers (models), HP vs Huawei routers (models), etc.
Does anybody has that presentation?
