Dear Lori, Now I will just try to get lisp tunneling working. From there I think I can understand the behavior and fix my issue.
I have two VMs. Vm1 and Vm2. Each of them have eth1 on them which are used to connect them. Before starting OVS and doing anything, I can ping other Vm successfully. As soon as I add this eth1 to a bridge that I created, the ping no longer works. In the lisp tunneling, it is shown that the ethernet port which connects the hypervisors are added to the bridge. Also I do not want to add a hypervisor in my lisp tunneling. I need to show tunneling between VMs and thus I think the need of a tap0 port is not necessary in my case. Please correct me if I am wrong.
