[cisco-voip] no QoS solution in WAN with L2VPN over FR!!!

Tue Jul 29 11:21:36 EDT 2008

Not sure if it would fit your need (or even work due to the multiple PVC¹s),
but could you apply a inbound CBFWQ on the Ethernet interface of the device?
You could at least make sure that voice traffic is prioritized before being
passed on to the other interfaces and then sent out to the FR cloud.  The
only issue is that you couldn¹t do it on a per-interface basis, but it may
still help as you could segregate voice from everything else.
