Hi <BR>
We experienced this problem a couple of years back and one major realization we made was that a lot of the providers out there were propagating routes with different prefix lengths from different points within their network as opposed to consistently propagating the exact prefix from the core outwards.<BR>

To be honest, I don't think this is the issue, Andrew.<BR>
<BR>
There a lot of operators in eastern and southern Africa that have capable hardware who are still routing inconsistently; be it inconsitent routing within Africa, or inconsistent routing between Africa and non-Africa interconnect points.<BR>
<BR>
If you ask me, a lot of operators in Africa place a higher significance on circuits that travel to Europe, than to those that remain within Africa (regional or in-country). <BR>
While this makes sense for traffic that does not natively reside within Africa, it does not make sense for traffic that can be picked up within Africa. But, unfortunately, this policy is extended to all links, regardless of whether they serve Africa or non-Africa traffic.<BR>
