Hi Team;

You have hub router - terminating two DLCIs under its subinterface -. One
of these DLCIs are connected to another router that have Tel sets connected
to it - the other spoke doesn't have any tel. sets - . So one
DLCI will carry the voice traffic.

The wording of the question is :

All the voice traffic through frame relay interface of R6 - R6 is
the hub router - should guarantee a bandwidth of 40kb/s . Each voice session
should have 20kb/s .

Hint: the command " ip rsvp .." is not enabled - or configurable -
with teh IOS image used .

My asnwer, and PLS correct me if I'm wrong :

!
interface serial 0/0
 frame-relay traffic-shapping
!
interface Serial0/0.1 multipoint
 frame-relay interface-dlci 406
  class ccie
!
map-class frame-relay ccie
 frame-relay voice bandwidth 40
 frame relay ip rtp priority 16384 16383 20
!

I don't think LLQ is a solution as LLQ takes affect only when there is
a congestion. Ofcourse CBWFQ is not a solution because it's not
giving any prioritization for any specific traffic like LLQ which places
a specific traffic in Priority queue.

PLS advice!

Ayman
