Hello, Glenn.

I already tried it, but they (Our ISP ) told me that they won't do it.
At first, they said that they will.  However, they said that they won't
do it later....

Then, I got this problem...

However, some ISP do NOT accept our route since the address belongs to traditional Class B address, and they told me that they only accept if we announce it as /16. (They filtered out our route…..)
