Why is it that we may want to configure PPP over Frame-relay,if both technologies are both layer two encapsulation techniques why do we use the two of them at the same time.For a moment i thought it is done to establish a secure connection between two end point by configuring ppp chap.
can somebody explain this.
We use PPP over frame relay for various reasons, mainly to benefit from the PPP features, authentication, MPPP, LFI and more, but both end devices must support it.
