[Lab4] No ICMP packets

[Lab4] No ICMP packets

Hello,

I know it is a bit late to ask questions about lab4 but I'm interested in the answer even if it comes after today.

I'm trying to follow the bonus section, everything looks to work well until Q21:

-In Q21 I don't see any ICMP packets in wireshark, the ARP works well and h4 get the mac address of h5 but don't send anything after that. Is it normal ?

-In Q22 I (think I) follow the instructions but the ping still doesn't work. A lot of logs are printed continuously in the RYU controller but nothing occurs and I try the ping command.

Any idea of what could go wrong ?

Thank you !

Hello,

 

As to Q21: you see the ARP broadcast, but you should not receive the MAC address of h5, if you receive it without doing any extra configuration, then you have something wrong.

 

As to Q22: this is the normal behavior and it is up to you to explain why you have these "Looping" logs

 

Good luck,

Alaeddine
