mininet> h1 ping h2 PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. From 10.0.0.1 icmp_seq=1 Destination Host Unreachable
what is the problem please ?
The L2Switch project provides Layer2 switch functionality.
Running the L2Switch project Check out the project using git
git clone https://git.opendaylight.org/gerrit/p/l2switch.git
The above command creates a directory called "l2switch" with the project.
Run the distribution To run the karaf distribution, you can use the following command:
./distribution/karaf/target/assembly/bin/karaf
NOTE: if karaf doesn't boot up to console,It is suggested to clear the contents of distribution/target/assembly/data/cache
To run the base distribution, you can use the following command
./distribution/base/target/distributions-l2switch-base-0.1.0-SNAPSHOT-osgipackage/opendaylight/run.sh
If you need additional resources, you can use these command line arguments:
-Xms1024m -Xmx2048m -XX:PermSize=512m -XX:MaxPermSize=1024m'
Creating a network using Mininet
sudo mn --controller=remote,ip=<Controller IP> --topo=linear,3 --switch ovsk,protocols=OpenFlow13
sudo mn --controller=remote,ip=127.0.0.1 --topo=linear,3 --switch ovsk,protocols=OpenFlow13
The above command will create a virtual network consisting of 3 switches. Each switch will connect to the controller located at the specified IP, that is to say, 127.0.0.1.
sudo mn --controller=remote,ip=127.0.0.1 --mac --topo=linear,3 --switch ovsk,protocols=OpenFlow13
The above command has the "mac" option, which makes it easier to distinguish between Host MAC addresses and Switch MAC addresses.
Generating network traffic using Mininet
h1 ping h2
The above command will cause host1 (h1) to ping host2 (h2)
pingall
'pingall' will cause every host to ping all other hosts.
