@habwe hi there, could you please describe the difference between Cisco and Huawei. in fact, the Cisco document said that In the default mode, IP-directed broadcast packets are not hardware forwarded; they are handled at the
process level by the MSFC2. The MSFC2 decision to forward or not forward the packet is then
dependent on the ip directed-broadcast command configuration.
There is no interaction between the ip directed-broadcast command and the mls ip directed-broadcast
command. The ip directed-broadcast command involves software forwarding and the mls ip
directed-broadcast command involves hardware forwarding.
I'm not sure if this is the difference you talked.
