== 7. Why doesn't ping work? ==
There are a variety of reasons why one node in CORE cannot ping another. First start with the sample imn configs if you have a new CORE installation. Make sure that you have installed Quagga for routing as mentioned in the [Quickstart]. For new installations, check that iptables is not blocking traffic on the host bridges (`iptables -L`). For MDR wireless routers, you'll need to install OSPF MDR as described in the manual. It may be helpful to `tcpdump` along the expected path to determine connectivity and routing information.
