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

Serial Link Compression

PPP Predictor:
Less CPU, more memory, less efficient.
R1(config-if)# compress predictor

HDLC Stacker (LZ):
More CPU, less memory, more efficient.
R1(config-if)# compress stacker

Frame Relay FRF.9 Compression
R1(config-if)# frame-relay map ip <IP-ADDRESS> <PVC> broadcast IETF payload-compression FRF9 stac one-way-negotiation

OSPF Frame-Relay Point-to-multipoint Host Routes


OSPF automatically adds a host(/32) route for neighbours on point to multipoint network. somehow serves as dlci map command.

R1:


router ospf 1
 log-adjacency-changes
 network 192.168.0.0 0.0.0.255 area 0

interface Serial1/0.1 multipoint
 ip address 192.168.0.1 255.255.255.0
 ip ospf network point-to-multipoint
 frame-relay interface-dlci 101
 frame-relay interface-dlci 102
 frame-relay interface-dlci 103



show ip route:


     1.0.0.0/32 is subnetted, 1 subnets
O       1.1.1.2 [110/65] via 192.168.0.2, 00:09:13, Serial1/0.1
     20.0.0.0/24 is subnetted, 1 subnets
O       20.20.20.0 [110/65] via 192.168.0.2, 00:09:13, Serial1/0.1
     192.168.0.0/24 is variably subnetted, 2 subnets, 2 masks
C       192.168.0.0/24 is directly connected, Serial1/0.1
O       192.168.0.2/32 [110/64] via 192.168.0.2, 00:09:13, Serial1/0.1
