Hi Sadiq Yakasai

Yes I can understand the EEK works fine for both interfaces.

But for the above question, we need to bring down the interface when the PVC
is goes down

If we apply EEK under the main interface and when the PVC is down, do you
thing EEK will bring down the main interface? Please advice

My Test:

Router R4 and R3 connected via FR

I have configured the multipoint sub interface on R4 and R3 and applied the
EEK under sub interface.

When I shut the R3 serial interface, then after the two EEK hello intervals,
the R4 sub interface also went down.

I did test without EEK on these sub interfaces, the R4 sub interface remains
up even though I shut the R3 serial interface. This proves to me that EEK is
bring down the sub interface when there is a PVC failure

I did the same test on the main interface with EEK enabled, but the serial
interface remain up/up when I shut the remote router serial interface

Map-class frame-relay e-2-e

R3:
