Obviously I can't comment as to what I personally saw in my Lab, but I can
say that it would be fair game within the scope of testing set forth by
Cisco.
RIPv2 does understand RIPv1 packets, but the opposite is not true. The RIPv2
header is different, containing fields for subnet mask and authentication.
If a v2 router hears a v1 speaker, it will reply in a v1 format, So in that
sense, there is some modest interaction between the two. This is no where
near as extensive as the interaction between IGRP and EIGRP speakers using
the same AS number.
In addition, there are interface commands that can be used to determine if
v1, v2, or both formats are used on that interface.
One cannot run more than one RIP process on a single router. So your router
will be either a v1 or a v2 speaker, but not both. In any migration scenario
the key is planning, based on understanding the existing structure, and
understanding the desired result.

WOW- good question !!! RIP Version 1 picks the configured interface Subnet
Mask to define it's Classful Network. RIP version 2 is Classless & carries
the Subnet Mask in it's updates. I have redistributed RIP Version 1 into
OSPF, but I'm not sure that knowledge totally applies. I wonder if version
1 & 2 must be redistributed or they connect much like IGRP & EIGRP. I'll be
reading & watching.
This sounds too much like something you might see on the CCIE lab :-0
