Hi..Everyone..
I am trying to config a FRTS for Multipoint-Subinterface.
But I was confused by this..!!
Who knows the correct configuration help me !!!!
Thanks.
----------
Diagram
----------
R2(S0 1.1.1.2)--FR--(S1.1 P2P)--R1-(S1.2 MP)---FR---(s0 2.2.2.3)-R3

FR
|
R4(s0 2.2.2.4)
-R1's S1.1 is a point-to-point interface & ip address is 1.1.1.1
-R1's S1.2 is a multipoint interface & ip address is 2.2.2.1
-R1's S1.2, R3's S0 & R4's S0 is in a same-subnet.
-R1,R2,R3 & R4 are coverd with a Frame-Relay.
-R1's S 1.1 has a 18Kbps Bandwidth
-R1's S 1.2 has a 36Kbps Bandwidth
---------
Question
---------
=Configure this FRTS on R1 !!
A>the CIR for PVC conecting to R2 should be 10Kbps
B>the CIR for PVC conecting to R3 should be 20Kbps
C>the CIR for PVC conecting to R3 should be 10Kbps
D>If BECNs are received, R1 should throttle back to 50% of the CIR
configured for the PVC that BECNs were received.
E>The "Peak rate" should be 30% higher than the CIR for each pvc
-----------
My Solution
-----------
1> The FRTS-config between R1's S1.1 & R2's S0 => Is this correct ??
R1>
interface Serial1
bandwidth 64
encapsulation frame-relay
frame-relay traffic-shaping **
no frame-relay inverse-arp
frame-relay lmi-type ansi
!
interface Serial1.1 point-to-point
bandwidth 16 **
ip address 1.1.1.1 255.255.255.0
frame-relay interface-dlci 614
class FRTS-P2P
!
map-class frame-relay FRTS-P2P
frame-relay mincir 5000
frame-relay traffic-rate 10000 13000
frame-relay adaptive-shaping becn
2> The FRTS-config between R1's S1.2(MP) & R3's S0
=>Is it right ??
**> Because R1's S1.2 is a multipoint sub-interface,
We must use a FR-Map command on R1 shch as below
R1>
interface Serial1.2 multipoint
bandwidth 38
ip address 2.2.2.1 255.255.255.0
ip ospf network point-to-multipoint
frame-relay map ip 2.2.2.3 603 broadcast **
frame-relay map ip 2.2.2.4 605 broadcast **
frame-relay class FRTS-MP **
=>This FRTS also affects to the R1-R4's PVC !!!
!
map-class frame-relay FRTS-MP
frame-relay mincir 10000
frame-relay traffic-rate 20000 26000
frame-relay adaptive-shaping becn
**NOTE**
**>There is a 2-PVCs in R1's S1.2
(One is connected to R3, The other is connected to R4)
**> How can i config a FRTS for the PVC of R1-R4 ???
**> The PVC between R1-R4 is also affected by the "frame-relay class FRTS"
(It's used for R1-R3's PVC)
=> So, 2-pvcs are affected by the "frame-relay class FRTS"-command on samee time
But I want to config a FRTS per PVC..
How should i do ????
Please Help me..!!
