Hi, “The router should be pingable, and should generate an ICMP echo reply in response to an ICMP echo request.” —— OpenFlow Tutorial – Create Router
Could you give me an example how to generate a ICMP reply message? I suppose that first create packet_base instance, then add ipv4 header, and then icmp header? Is there a way to copy necessary information from ICMP request to reply message, and then modify some attributes? How about ICMP unreachable message? Thanks, Weiyun
