‎12-03-2014 08:35 PM - edited ‎03-05-2019 12:17 AM

Hi! I am studying for my CCNA and need some help.  I am configured frame relay mulipoint over eigrp psuedo broadcast in a hub and 3 spoke topology. hub can ping accross to all spokes but spoke are unable to ping each other. I disable spilt horizon on hub and disabled auto summary on all routers. any suggestions? doing sho ip route i see the routes on the spokes for each other. 

 

Thanks for you help!

How are the spoke routers configured on their frame relay interface?

 

What is in the frame relay map of the spoke router?

Thanks for the additional information. your problem is that the spokes have map entry only for the hub but not for other spokes. You need to add map entries for the other spokes.

you need these commands on spokes: 201 is hub DLCI and 192.168.100.3 is spoke ip

frame-relay map ip 192.168.100.3 201
