ping: unknown iface

ping: unknown iface

Hello

I am getting the following in Lab 2:

mininet> h1 ping6 -I h2-eth0 fe80::682d:bcff:fe38:2598
ping: unknown iface h2-eth0

I don't understand what I could be doing wrong. I have been stuck on this for a while. I thought I was pinging in the same way as was done in Lab 1.

The intfs command outputs the following

h1: h1-eth0
h2: h2-eth0
h3: h3-eth0
h4: h4-eth0
s1: lo,s1-eth1,s1-eth2,s1-eth3
s2: lo,s2-eth1,s2-eth2,s2-eth3
s3: lo,s3-eth1,s3-eth2

Hello Valentin,


The command is:

#ping6 -I h1-eth0 fe80::682d:bcff:fe38:2598

that should be run on terminal of h1; or via mininet CLI as:

mininet> h1 ping6 -I h1-eth0 fe80::682d:bcff:fe38:2598


You should not put destination interface (i.e. h2-eth0) in your command. 


Best,

Ehsan
