Probably just an amateur concern, but can someone explain this to me:
BTW: our AS is 7271. I have three peers, AS816, 3804 and 6463. They all
talk to one another at AS577. In the output below, I see that only two of
my neighbors are advertising this route to me. The third one, AS6463
should also be advertising this to me as he talks to AS577 and he should
be hearing the advertisment from that AS and I should be hearing that from
him.

* 9.20.0.0/17 206.47.45.128 60 0 3804 577 3561 2685 2686 ?
*> 205.150.206.65 60 0 816 701 2685 2686 ?

Here's another one:

* 12.10.231.0/24 206.47.45.128 60 0 3804 577 3561 5696 7369 i
*> 205.150.206.65 60 0 816 701 6113 5696 7369 i

AS6463 should hear that route from 3561 1239 6463 7271.

* 13.0.0.0 206.222.95.53 30 0 6463 1239 1 i
*> 206.47.45.128 60 0 3804 577 3561 1 i
* 205.150.206.65 40 0 816 701 1 i

Here's ont that's perfect.

Anyone know why things like this happen?
