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...

Hello Kenji,

Do you have your own AS number?  Unless I am mistaken, if you do ,the
easiest solution would be to advertise both your /17's vis BGP to your
ISP.  So long as they accept them and aggregate your /17's into a /16 you
should have no problems...

Hi, All.

I'm having problem with our class B address.  Last month, we tested our class B address.  We announce the address 
as 2 x /17 from 2 different POP under the same ISP's data center.  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…..)

I talked to some people, they suggested me that we need to announce the block as /16 from both POP, even though we 
only like to announce /17 from each POP (Front /17 from one POP, the other /17 from another POP.).

How could we do so ?  Please help us.

|--------- |
| POP A    |
| /17      |------|
|----------|      |     |--------|
                  |-----| ISP C  |-- Internet---X----ISP D
| ---------|      |     |--------|           Filtered out here…
|  POP B   |------|      
|   /17    |
-----------
