I'm working on a project for school we are using 5 routers in a star layout with a main hub, i managed to config FR into all the routers and they all ping each others interfaces just fine, my problem is that i can't ping through the ethernet intefaces, i can ping the interface itself but not the devices connected to it.

a picture is worth a thousand words:

Hi,

-With frame relay mappings you should always remember to map a remote ip address to a local dlci.

Example: for your HUB's s1/1 interface, the frame map statement should be:-

frame-relay map ip 20.0.1.1 102 broadcast
frame-relay map ip [remote ip] [local dlci] broadcast

-Mixing dynamic mappings with static mappings is not a good idea so turn off inverse-arp at each serial interface.

-Only one type of statement per interface is enough. So for instance, if you put frame-relay map ip 20.0.1.1 102 broadcast you don't have to put frame-relay interface-dlci 102 in there as well.

thanks for the help, i actually got it to work by removing auto summary
