Interesting question. I don't believe that this can be done with a normal
acl. I just tried it in the lab and the interface and mapping to the switch
and end-points continue to stay up. Which I would expect these would since
the keepalive is not based on the layer 3 or above. The keepalive is based on
the frame-relay signalling that occures between the switch and the end-user.

Is it possible to have ACL deny the keepalive packets?

You can do it through the acl, you can allow your routing protocols (if that
is what you want to do). Or, simply stop all protocols. You cannot shut down
an interface and turn it up again with the acl (hardware, wise). For that,
you would want to look into the kron application (something I need to look
into more myself).

So you mean Interface status up/down after apply time-range

You can do the same with any type of interface....essentially, you are simply
stopping the traffic (or whatever type of traffic you want). Give it a try in
the lab.

Okay, but thats more for a dialer interface, how do you apply it to a point
to point circuit?

Take a look at time-ranges applied to an ACL. HTH.

Hello
Any clue for this scenario?
Configure RouterA and RouterB so the serial interface is not up during
working
hours of 5pm and 6am.
