Hello Group,
I got frame relay scenario that is just about done but would like some
input on solutions...
Here is a scenario statement put forth for user to configure:
On the link between r1 & r3, any packet exceeding 30kbps should be set
for discard eligibility.
See diagram at
http://www.rantwear.com/netwrks/frame_cloud_2.jpg
the file is low bytes so it should load quickly
Here is the physical topology:
Inverse ARP is not be used at all. That is disabled on each router.
Consist of four routers
r1, r2, r3, & r4
r1 & r3 are point-to-point,
r3,r2, &r6 are multipoint
r3 serial 0 two subinterfaces configured.
r3 s0.2 on 180.1.40.0/27
r3, r2 & r6 configured multipoint r3 is hub
network 180.1.40.0/27
r3 = 180.1.40.3, r2=180.1.40.2, r6=180.1.40.6
r3 serail 0.1 point-to-point
network 180.1.128.0/28
r3=180.1.128.3, r1=180.1.128.1
r3 is a 4000m
r1,r2, r6 are 2500 series routers each with 2 serials and 1 LAN
interface
The frame switch is a Cisco 2521 configured full mesh
Each interface is configured with 3 DLCI's
The network is up and pings are as they should be.
I'm looking for assistance on the point-to-point between r3 & r1.
Here is a suggested configurations for serail 0 on r1 (cisco 2504) that
I disagree with:
at r1:
interface Serial0
ip address 180.1.128.1 255.255.255.240
no ip directed-broadcast
encapsulation frame-relay
ip ospf network point-to-point
no ip mroute-cache
logging event subif-link-status
logging event dlci-status-change
frame-relay de-group 1 103
frame-relay map ip 180.1.128.3 103 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
at global configuration mode the command:
frame-relay de-list 1 protocol ip gt 30
At r3
Serial 0.1
interface Serial0.1 point-to-point
ip address 180.1.128.3 255.255.255.240
no ip directed-broadcast
ip ospf network point-to-point
frame-relay de-group 1 301
frame-relay interface-dlci 301
at global configuration mode the command:
frame-relay de-list 1 protocol ip gt 30
My inclination is to use the following:
interface Serial0
ip address 180.1.128.1 255.255.255.240
no ip directed-broadcast
encapsulation frame-relay
ip ospf network point-to-point
no ip mroute-cache
logging event subif-link-status
logging event dlci-status-change
traffic-shape rate 15000 30000 30000 1000
frame-relay map ip 180.1.128.3 103 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
This was recommended to me by CCIE months ago.
Any suggestions welcomed.
Thank you.
Regards,
Ken Le
