Unsolved cisco IOS based frame-relay questions.

Hi, all!

----------------------------------------------------------------------------------------------------
? Which clock rate should be assigned to DCE commonly?

! "no arp frame-relay" is a deprecated and abandoned command so it is
useless and unfunctional in most versions of IOS.
 It does NOT act as the rumour said "stop to response the inverse-arp
request from other end".

? Does frame-relay subinterface inherit the inverse-arp behavior from its
parent frame-relay physical interface?
 Does this inheritance act differently between point-to-point subinterface
and point-to-multipoint subinterface?
? When parent frame-relay physical interface encapsulated in IETF standard,
what happens actually if "frame-relay interface-dlci {dlci-number}" command
without "ietf" keyword entered?
 We can observe the difference between with and without "ietf" keyword under
the command "show frame-relay map", and in both conditions ping works.

! means solved, where ? means unsolved.

Does anybody meet these questions before and did some experiments to prove?

Thanks!
