Is there any possibility of sending echo request (GTPC) with the sequence number as zero?

Section 5.3/29.274
" The GTPv2-C message header for the Echo Request, Echo Response and Version Not Supported Indication messages
shall not contain the TEID field, but shall contain the Sequence Number fields, followed by one spare octet as depicted
in figure 5.3-1"

Now my question - Is there any possibility of sending echo request with the sequence number as zero?

As per my knowledge, sequence number is used to track re-transmission and to detect link failure in case expected response message is not received. Since this is used to track re-transmission it should be non-zero number.

GTP-U - How the restarts in GTP-U entity are detected if no break in receiving Echo Rsp from peer GTP-U entity?

This is regarding the scenario where GTP-U peer got restarted and again came to service. However,the other GTP-U entity could not detect the restart of peer GTP-U entiity as it keep receving Echo Response. I had read the Restart Counter/(Recovery IE), is used to detect such restarts. But, as per spec 29.281, Restart counter is no longer use and ignored. In such case how such quick GTP-U restarts are detected by peer GTP-U? Is it so that in this case no recovery action needed for User Plane ?

I do see that we have Private Extension IE but again that is vendor specific so that can not be used for interconnection with devices with other Vendors.
