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... Kenji On Thu, 18 May 2000 17:34:46 -0400 (EDT) Glenn Staniforth <glenns@UUNET.CA> wrote:

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 | -----------
