 Description   

Ran into following exception when trying to configure VPnInterface when using vpnservice with openstack/OVSDB.

When using mininet dpnId is within range for 'long' but with OVSDB it uses a dpnid which is bigger than that. Note that most physical switches use a combination of mac-address and/or some other parameter to generate DatapathId, so dpnId will most of the times be bigger than range for long.

Correction: long is 64bit, so that is not the issue. Problem is that l3nexthop.yang defines dpnId as uint32:

rpc getEgressPointer {
description "returns egress pointer, an OF Group Id";
input {
leaf dpnId

{type uint32;}
leaf vpnId { type uint32;} /* optional */
leaf ipPrefix {type string;}
leaf nexthopIp {type string;}
}
output {
leaf egressPointer {type uint32;}


leaf localDestination

{type boolean;}

}
}

So, when trying to set a dpnInd with bigger value than uint32, it is causing this exception.
