I completely disagree with you.
Multiple links may have failure modes in addition to and identical to some of the failure modes of a single connection, but multiple links also removes a complete calls of failure modes associated with a single connection.
This is a pretty fundemental tenet of communications systems in general as is not limited to IP.
Well, teoretically this is certanly true. However, looking at reality, I don't think this is wort an extra entry in the global routing table, and where do this stop? How about the SOHO user that I described? Why are not they allowed broken up PA or PI space to be multihomed? - kurtis -
