One better solution is to take advantage of route tags or labels. When a route is redistributed you tag it, and then when mutual redistribution occurs in the other direction, you exclude routes that have that tag. You'd need to do this in both redistribution directions, with different tags to prevent loops in either direction. This method doesn't rely on the behaviour of always increase metrics, so it would be more robust.
HTH, Mark.
I dont believe popular vendors implementations of rip propogate tags. At least the last time I tried loop prevention with that, it didnt work.
