Why can I not ping from Router to Router (example attached)?

[mahed60822]

I'm trying to ping from router "DC_GE" to Router "BE":

The packet tracer file is linked.  Any help would be greatly appreciated, thanks a lot!

Best regards

Hello, 

make sure that on the GE and the BE routers, you have:

network 10.0.10.0 0.0.0.255 area 0

configured...

Hi @mahed60822 

Try this 

Router GE

ospf 10

network 10.0.10.2 mask area 1

Hello,

there was a lot missing in your configuration, such as some routers not running OSPF at all, a missing default route on the ISP router, and missing network statements on the routers that actually do have OSPF running. On the BE router, you need a static default route towards the ISP, and under the OSPF process, you need 'default-information originate' in order for that default route to get propagated to all the other OSPF routers.

Have a loo at the revised file, where end to end connectivity has been established....
