I am new in mininet and I want to know while I create spin leaf DataCenter topology and visualiz the topology using RYU controller the ping is not working. The Topology:

                       ____[S1]    
[L1], [L2], [L3]------|
                      |----[S2]

3 hosts are attached to each Leaf switch, and each leaf is connected to both Spine Switches. The hosts doesn't ping on each other.

Probably you have some loop in the topo, so make sure to use RYU with STP protocol

The STP protocol can take some minutes (depends on the topology). This is how I run Ryu with STP (I am using the python3 and OpenFlow 1.3, if you use a different version the path can be different)

ryu-manager /usr/lib/python3/dist-packages/ryu/app/simple_switch_stp_13.py --verbose
