Re: Peering Table Question

Intelligent aggregation techniques break MEDs and therefore introduce
a need for advertisement of more-specifics in order to convey the 
optimal entry point into an AS.

Then...  Poor address allocation/aggregation models and broken IGP 
metric -> BGP MED associations, coupled with fear that the peer 
network will "leak the more specifics", make questionable the value 
of MEDs, especially for "well established TIER 1" providers with 
tons of legacy stuff or a really large customer base.

or why dont you require both to peer in 4 - 6 places in the US and honor meds
both ways. This way, each is carrying traffic on their network. Of course the
bigger providers dont want this as they would lose losts of $$ from all the
payments they get for 'transit'.
