max-reserved-bandwidth

To change the percent of interface bandwidth allocated for Resource Reservation Protocol (RSVP), class-based weighted fair queueing (CBWFQ), low latency queueing (LLQ), IP RTP Priority, Frame Relay IP RTP Priority, Frame Relay PVC Interface Priority Queueing (PIPQ), or hierarchical queueing framework (HQF), use the max-reserved bandwidth command in interface configuration mode.

Frame Relay RTP Priority

map-class frame-relay <NAME>
frame-relay ip rtp priority <LOW PORT NUMBER> <PORT RANGE> <BANDWIDTH>

Don't forget to configure frame-relay fragmentation (FRF.12) as RTP Priority doesn't work without frame-relay fragmentation.
map-class frame-relay <NAME>
frame-relay fragmentation <SIZE>

Frame Relay Traffic Shape

R1(config)# map-class <CLASS-NAME>
R1(config-map-class)#frame-relay cir <CIR>
R1(config-map-class)#frame-relay bc <CIR>
R1(config-map-class)#frame-relay be <CIR>
R1(config-if)# frame-relay traffic-shaping

Apply to PVC:
R1(config-if)# frame-relay interface-dlc <PVC>
R1(config-fr-dlci)#class <CLASS-NAME>

Apply to interface:
R1(config-if)# frame-relay class <CLASS-NAME>


CIR=Bc/Tc

Be=(AR-CIR)*Tc

AR= Available Rate, the actual physical interface speed.


Don't forget to enable traffic shaping on interface first

R1(config-if)# frame-relay traffic-shaping

Don't Miss the Permit Sequence in route-map

While modifying BGP route attributes with route-map, always remember to add permit line at the end of the list, or you'll end up filtering those routes which haven't been matched by previous route-map entries.
