From: Tony Li <tli@jnx.com> > We need to move to a routing architecture where maps are distributed, > *not* routing tables. Exactly how does this prevent the exchange of bad information? Well, a full-scale explanation is a major tome (we can explore that on Big-I in more detail if you want), but *briefly*, the idea is that you can i) prevent lots of kinds of bad information, and ii) deal much better with the kinds you can't stop. For instance, use of public key cryptography can prevent anyone else from originating bad information about connectivity inside or to X - their map updates will not be correctly signed with X's private key. Only "auhorized" agents of topological entity X (i.e. those allowed to distribute maps or abstractions of X, outside X) have the key to sign map data about X. (X and Y can still cooperate to lie about having connectivity between them, when in fact they do not, but you can (albeit with some work) detect that and work around it, if you have not only a map distribution system, but explicit routing too.) It can certainly prevent all unilateral bad information, i.e. based on someone incorrectly configuring their routers (or software/hardware bugs). Noel
