Eigrp troubleshooting

[leoaraujo79]

Hi  I am doing a lab on using packet tracer and do not know where is the problem.

The network has a central (hub) router conecting 4 routers (spokes).

I can go in to global configuration mode only in one of the spokes and in the central router.

The central router has all its direct networks listed on the eigrp AS 30

The spoke router I configured my self with As 30 and the network statements.

show running on the other spokes routers do not show any network listed under AS 30.

I can not ping some of the interfaces on this other spokes routers.

Where should I check next.

Someone told me that it could be   eigrp stub setup but I never learn nothing about it.

Help please!!!!!

Hi Leandro,

     Did you set the point-to-multipoint network on your lab? If so, you need to disable Split Horizon on the point-to-multipoint interface on Hub router. It's enabled by default.

HubRouter(conf)#interface Serial xxx

HubRouter(conf-t)# no ip split-horizon eigrp as-number

    However,eigrp stub is different. You can lap it up after beating this lab. (grin)  

HTH,

Toshi

After all the problem was on a passive interface that I did not look properly.

The router on the center of my lab had a passive interface and did not send any information there.
