Your page is what sprint will or will not accept. The problem you have is that BT is advertising the prefix to Sprint with the no-advertise community. That means Sprint is getting the prefix, but Sprint, not BT, will not advertise the prefix. It is BT that is multi-homed, not the customer, and you are not even trying to prevent the advertisement of that prefix from BT, only from Sprint.

I can tell you that any AS is completely free to ignore the hints, suggestions, advice, etc. from other ASes. That is why they are Autonomous Systems; they are autonomously managed. | |

| Dec 2, 2016 at 18:31 | comment | added | Daniel | Actually Ron some services do offer community attributes that block advertisements to certain geographical areas or other service providers | |
| Dec 2, 2016 at 18:30 | comment | added | Ron Maupin♦ | The problem with your approach is that one AS cannot dictate to another AS. Any AS is free to ignore anything a peer AS wants. It requires a business arrangement between the ASes to achieve what you want. It is completely up to BT what prefixes it does or does not advertise to any peer, and CUSTOMER really has no say over that, absent a contractual arrangement. | |
