[e2e] Question on XCP

[Arjuna Sathiaseelan]

Dear All,
  I would be very much obliged if anyone could let me know how a XCP
sender determines whether all the routers in its path is XCP enabled?
The XCP sender works only if all the routers in its path are enabled
with XCP.

I have a mechanism similar to XCP which requires all the routers in its
path to be enabled with the mechanism proposed by me. Thanks.
Regds,
Arjuna
