EIGRP Routes

[Cjp0116]

I've made an point-to-multipoint frame-relay network, one with typical hub and spoke. While each spoke's EIGRP routes are being shown in the routing table, connectivity can't be established.

R1 (HUB)

interface Loopback0
ip address 1.1.1.1 255.255.255.0

interface Serial2/1
ip address 172.12.123.1 255.255.255.0
no ip split-horizon eigrp 1
encapsulation frame-relay
serial restart-delay 0

router eigrp 1
network 0.0.0.0

R2 (Spoke)

interface Loopback0
ip address 2.0.1.2 255.255.255.0
!
interface Loopback1
ip address 2.0.2.2 255.255.255.0
!
interface Loopback2
ip address 2.0.0.2 255.255.255.0
!
interface Loopback3
ip address 2.0.3.2 255.255.255.0

interface Serial2/2
ip address 172.12.123.2 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
frame-relay map ip 172.12.123.2 301 broadcast
frame-relay map ip 172.12.123.1 201 broadcast

router eigrp 1
network 0.0.0.0

R3 (Spoke)

interface Serial2/3
ip address 172.12.123.3 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
frame-relay map ip 172.12.123.2 301 broadcast
frame-relay map ip 172.12.123.1 301 broadcast

interface Loopback3
ip address 3.3.3.3 255.255.255.255

router eigrp 1
network 0.0.0.0

I've disabled split horizon on the hub router, and R2 has R3's eigrp routes in the topology table and vise versa. Yet I can't ping any of them

Hello,

make sure you have auto-summary disabled on all your routers. It should be visible in the running config once you have that configured:

router eigrp 1
network 0.0.0.0
no auto-summary

Also, how are the DLCIs mapped in your cloud ? Post the Packet Tracer project file (.pkt). ZIP it first otherwise the system won't let you upload it...

How are you configuring these setup, is  this using any GNS3 / Eve / IOU  ? 

The communication failed  because of missing frame relay mapping information on the hub.
