I picked this up from the link below - I still have questions on how NLSP
interacts w/ EIGRP - but I an guessing the interaction with RIP is very
similar to EIGRP.
By default, the router redistributes IPX RIP routes into IPX enhanced IGRP,
and vice versa. When routes are redistributed, a RIP route to a destination
with a hop count of 1 is always preferred over an enhanced IGRP route with a
hop count of 1. This ensures that the router always believes a Novell IPX
server over a Cisco router for internal IPX networks. The only exception to
this rule is if both the RIP and enhanced IGRP updates were received from
the same router. In this case, and in the case of all other RIP metrics (2
through 15), the enhanced IGRP route always is preferred over the RIP route
when the hop counts are the same.
Internal enhanced IGRP routes are always preferred over external enhanced
IGRP routes. This means that if there are two enhanced IGRP paths to a
destination, the path that originated within the enhanced IGRP autonomous
sytem will always be preferred over the enhanced IGRP path that originated
from outside of the autonomous system, regardless of the metric.
Redistributed RIP routes are alwaysadvertised in enhanced IGRP as external.
