Hello Group,
I got frame relay scenario that is just about done but would like some
input on solutions...
Here is the physical topology.
http://www.rantwear.com/netwrks/frame_cloud_2.jpg
the file is low bytes so it should load quickly
Inverse ARP is not be used at all. That is disabled on each router.
Consist of four routers
r1, r2, r3, & r4
See diagram at
http://www.rantwear.com/netwrks/frame_cloud_2.jpg
the file is low bytes so it should load quickly
r3 serial 3/0 two subinterface 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 s0.1 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.
I'm looking for assistance on the point-to-point between r3 & r1.
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.
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
Likewise at r3 s3/0.1
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
