Did you do fragment and appropriate shaping on both sides or just the
hub?

Hi Team,
Does anyone sees anything wrong with this config?
R2 (FR Hub) ---- R4 (Spoke)
I am running the following FRTS on R2:-
interface Serial0
no ip address
encapsulation frame-relay
clockrate 2000000
frame-relay traffic-shaping
frame-relay lmi-type ansi
interface Serial0.2 multipoint
ip address 192.168.24.2 255.255.255.248
ip router isis
frame-relay class test
frame-relay map clns 104 broadcast
frame-relay map ip 192.168.24.4 104 broadcast
no frame-relay inverse-arp
map-class frame-relay test
frame-relay cir 256000
frame-relay bc 2560
frame-relay be 0
frame-relay mincir 256000
no frame-relay adaptive-shaping
frame-relay ip rtp priority 16384 16383 48
The 2 routers are running ISIS, and they seem fine.
Now, the practice lab scenario's requirment goes...
"the users are complaining about serialization delays across the FR
network and about latencies" You are not allowed to used any ACL
anywhere..."
I take that as meaning using FRF.12 (Fragmentation)
So I added the fragment to my map-class... but as soon as I did that,
ISIS fails and doesn't want to come back =(
map-class frame-relay test
frame-relay cir 256000
frame-relay bc 2560
frame-relay be 0
frame-relay mincir 256000
no frame-relay adaptive-shaping
frame-relay fair-queue
frame-relay fragment 320
frame-relay ip rtp priority 16384 16383 48
r2#sh clns neighbors
System Id Interface SNPA State Holdtime Type Protocol
r4 Se0.2 DLCI 104 Up 7 L2 IS-IS
r2#
r2#sh clns neighbors
System Id Interface SNPA State Holdtime Type Protocol
r4 Se0.2 DLCI 104 Init 7 L2 IS-IS
r2#
...and a similar FRTS config on R4. I have tried disable the FRTS on R4
(so just running FRTS on R2)... but same problem. In other words, as
soon as I add fragment, then ISIS breaks.
Would be greatly appreciated to those who took their time to explain
this to me... I have spent ages on this already...
Thanks,
H.
