Becky,
I believe you have a wrong calculation.
Area 256 is Area 0.0.1.0
Which is 2 to the power of 8 and in binary:
0000 0001 0000 0000 for the last two octets. Please check your calculations
for 65536 also.
Rgds.,
Burst

Please respond to
"Becky Qiang"
I think it is convertable. As we all know that there are two different
forms
to enter the area ID, one form is in from 0 to 4,294,967,295; the other is
0.0.0.0 to 255.255.255.255. They are convertable with each other. For
example, if I configure area ID as 256, the equivelent form in x.x.x.x is
0.0.1.255, which is 2 powered by 8. Here is another example, for area ID
65536, the equivelent x.x.x.x form is 0.0.255.255, which is 2 powered by
16.
So, area 0 and area 0.0.0.0 is the same. Only when you go beyond 255 (which
overflows the last octet), then you need calculation.
Becky
