In case you've missed a few SIGCOMMs...


BGP has serious problems
Easily misconfigured [Mahajan2002]
Forwarding loops [Dube1999]
Persistent route oscillation [Griffin1999, Varadhan2000]
Slow convergence/suppressed routes [Labovitz2001, Mao2002]
Useless routing messages [Labovitz1999, Wang2002]
Security weaknesses [Beard2002, Kent2000]
For every aberrant behavior, 
a useful lesson and a point solution.  

Can we build on these lessons to:
express exactly what's wrong with BGP (or its configuration)
reason about proposed fixes, design modifications, etc.
