Hi Everyone, I am working with mininet and ovs. For my experiment I added a link between the mininet switch and global namespace of my virtual machine where my controller resides. Relevant interfaces of this link on both sides (global namespace and inside mininet) are up and running.
Problem is this switch can not connect to the controller in the global namespace. As per my understanding, the switch will try to reach controller from all of its interfaces. I checked and found following- mininet> sc1 tc -s -d qdisc show dev sc1-ethc qdisc noqueue 0: root refcnt 2 Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 mininet> sc1 tc -s -d qdisc show dev sc1-eth2 qdisc htb 1: root refcnt 2 r2q 10 default 0x1 direct_packets_stat 0 ver 3.17 direct_qlen 1000 Sent 3812 bytes 32 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 mininet> sc1 tc -s -d qdisc show dev sc1-eth3 qdisc htb 1: root refcnt 2 r2q 10 default 0x1 direct_packets_stat 0 ver 3.17 direct_qlen 1000 Sent 3883 bytes 33 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 As it can be seen there is no pkt passing via interface sc1-ethc, which is connected to the controller in the global namespace. Although all other interfaces are trying to connect to the controller. Could anyone please help me to understand why it's happening and how to overcome this situation? Thank you. Kind Regards- Sudhanshu Naithani
