[c-nsp] Rate-limit on Frame Relay T1

[Daniel Holme]

Personally, on a frame-relay interface, I would use frame-relay
traffic shaping to achieve bandwidth control as it's integral to the
FR config and you can apply it to the DLCI directly.

You're running PPP over the DLCI in your example, so you should
probably do any rate-limiting at that level, ie, in the
virtual-template.

Do you see your egress policy 'QoS-Out' matching any packets?
