Customer have two NE40 routers in the network and the VRP version is V300R002C01B533
They were facing DOS attacks on these routers.
They tried to block these attacks by defining some rules on these
routers but we cant.
Following were two solutions to block these attacks.
1: Update routers to V3R3 version because current version V3R2 does
not support Anti DOS attacks.
2: Add Huawei Eudemon firewall into network. Eudemon 1000/8000
series can defend DDoS attack at metro access/core layer
