I am trying to use a pair of OVS for an ERSPAN link. On the first OVS, I configure ERSPAN per the following:
ovs-vsctl add-port data at_erspan0 -- set int at_erspan0 type=erspan options:key=1 options:remote_ip=192.168.1.30 options:erspan_ver=1 options:erspan_idx=1 The traffic is sent ERSPAN encapsulated to 192.168.1.30. However, when it comes to decapsulating, that is where my problem is. If I create an erspan interface, with the remote ip of the first OVS, then the problem I get is that essentially the traffic appears to be a loop. If I do not create the ERSPAN interface on the 2nd OVS, then I am unable to decapsulate the traffic. Is there a setting to prevent this loop or to drop the traffic so we do not get a loop, but I am able to decapsulate the traffic? Dennis Heim | Technical Solutions Architect INTERNAL INTERNAL
