Hi, everyone!
In line 1649 of ospf6_message.c (\quagga-1.2.4\ospf6d), it says that "/* checksum is calculated by kernel */" as following. I am wondering which part of the kernel calculate the OSPF header checksum? In Sockets layer or IPv6 layer? And in which file of what kernel? /* fill OSPF header */ oh->version = OSPFV3_VERSION; /* message type must be set before */ /* message length must be set before */ oh->router_id = oi->area->ospf6->router_id; oh->area_id = oi->area->area_id; /* checksum is calculated by kernel */ oh->instance_id = oi->instance_id; oh->reserved = 0; Thanks in advance! Regards, yanhc
