????: [Ryu-devel] Ryu controller have problem with forward packets intopology
with two links between switches
Welcome
Ryu controller have problem with forward packets in topology with two
links between switches. Below simple topology and logs from
controllers. Maybe you know how to solve this?
---
mininet topology

"""Custom topology example
Two directly connected switches plus a host for each switch:
host --- switch === switch --- host
Adding the 'topos' dict with a key/value pair to generate our newly defined
topology enables one to pass in '--topo=mytopo' from the command line.
"""
from mininet.topo import Topo
class MyTopo( Topo ):
"Simple topology example."
def __init__( self ):
"Create custom topo."
# Initialize topology
Topo.__init__( self )
# Add hosts and switches
leftHost = self.addHost( 'h1' )
rightHost = self.addHost( 'h2' )
leftSwitch = self.addSwitch( 's3' )
rightSwitch = self.addSwitch( 's4' )
# Add links
self.addLink( leftHost, leftSwitch )
self.addLink( leftSwitch, rightSwitch )
self.addLink( leftSwitch, rightSwitch )
self.addLink( rightSwitch, rightHost )
topos = { 'mytopo': ( lambda: MyTopo() ) }
