Hi all:
Now I configure sfc in the odl integrated with openstack.
The openstack environment is :
compute1 and compute2, the two computes are both physical servers.
A vm of the compute1 sends a icmp packet, when the packet arrives
the br-int of the compute1, it will be encapsulated vxlan-gpe-nsh, and
sent to the compute2.
But the strange problem is if the size of icmp packet< 130
byte(vxlan-gpe-nsh packet <260), the communication is normal. If the size
>130, after arriving compute2 ,the flow table not match the packet., and if
ping several times, the network and ovs of compute2 collapse ：The network
connection goes down for one minute,and one minute later the network
recovery;The ovs stop and the kernel module is deleted; All the OVS br-int
virtual machine tap port is deleted, unable to connect to the ODL
controller.
If the icmp packet is not encapsulated by vxlan-gpe-nsh but only
vxlan-gpe, no matter what the size is ,the communication is normal.
And if compue1 and compute2 are not physical servers, but the virtual
machine, regardless of the size of ICMP packet , through the
vxlan-gpe-nsh encapsulation the communication is normal. It is that now
the physical environment has above problems, but the virtual environment is
normal.
so can you tell me how to solve the problems? Thank you !
Glend ren
best regards.
