Hi All,
As we all know that, contrail system could provide vxlan encapsulation 
communication between two VMs in  two different Computer nodes. At the same 
time we cloud allocate Floating IP from public networks which is external to 
public network by Simple GateWay using GRE/UDP Encapsulation. If we changed the 
encapsulation type into vxlan, The vm could not access the public by Simple 
gateway. the vrouter in Simple Gateway node reported invalid VNI.
I want to know was there someone did layer3 vxlan gateway successfully with 
Simple Gateway or other switch. The Juniper provided the TORAgent solution to 
communication with OVS by ovsdb protocol. This implemented lay2 
inter-communication between virtual networks and physics network. but it did 
not provided layer 3 access function.
If you have other similar method and share with me, that's very great.
Thanks
Andy Wang
