Cisco uses RPL (Route Policy Language) while Huawei uses XPL (Extended Route Policy language). Basically they are the same concept but of course the commands are slightly different, though editing the policy or prefix-set requires vi/vim knowlege.

uRPF or Unicast Reverse Path Forwarding is a security feature/tool that help verifies reachability of source address in packets being forwarded. It can prevents malicious and spoofing attacks as it will perform forwarding table lookup on the source IP address. – it as defined in RFC3704 – it follows RFC2827 for ingress filtering. – it relies on the CEF (Cisco Express Forwarding) or FIB table to perform lookups. – preferably implemented at the network edge facing internet, customers and servers…

As per Cisco documentation: A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus devices to appear as a single Port Channel to a third device. The third device can be a Cisco Nexus 2000 Series Fabric Extender or a switch, server, or any other networking device. A vPC can provide Layer 2 multipathing, which allows you to create redundancy by increasing bandwidth, enabling multiple parallel paths between nodes and load-balancing traffic where alternative paths…
