So I have an exercise with this topology: [![enter image description here][1]][1] Here is the routing table of the ABR: [![enter image description here][2]][2] I have configured all the OSPF networks on each router and I made every g0/0 interface (except for the ABR in the middle) a passive interface. However, I cannot ping from PC11 to PC1 (or any other PC in another area). As you can see in the routing table; PC11 only knows the devices in his area...is that normal? Shouldn't it also know the devices in the other area? What am I missing here? Thanks in advance. [1]: https://i.sstatic.net/NXVpF.png [2]: https://i.sstatic.net/BGHBA.png
