<br>
First time post, so I hope this is the appropriate query for this list.<br>
<br>
I'm trying to steer incoming traffic to our 3 x /24 networks via Testra as primary carrier. On secondary link (nextgen) we use multiple AS path prepend on the BGP configuration.<br>
<br>
Outgoing routing is fine, however incoming we still have substantial amount of traffic come in secondary link. (approx. 50%)<br>
<br>
Telstra think they are advertising correctly to internet and other carriers are overriding the advertisements based on commercial reasons.<br>
<br>
Nextgen doesn't think Telstra are advertising correctly domestically.<br>
<br>
Using the looking glass tools, it looks like places like iinet are learning networks only via nextgen.<br>
Telstra say optus looking glass shows network learnt ok via Telstra.<br>
Iprimus seems to be the only one that has both, but prefers nextgen advertisement.<br>
AAPT tracert goes via Telstra.<br>
<br>
Thanks<br>
Peter.<br>
