Another difference between IOS <strong>and</strong> NX-OS behavior can be seen in the way OSPF shows<br />

the area number. In the preceding examples, the area designator is entered as area 0;<br />

however, this shows up as area 0.0.0.0 in the output. As demonstrated in Example 3-38, this<br />

behavior does not impact the actual functionality of OSPF as shown between an OSPF<br />

router running IOS <strong>and</strong> a router running NX-OS.<br />
