That is exactly right, Joe. However, the question seemed to be asking how you
can configure R2 and R3 to never become DR's after a re-election. You are
absolutely correct in stating that the other two routers will never form an
adjacency though.

Let me play Devil's advocate for a minute.
If R1 dies and both R2 and R3 have their priorities set to 0, then who
becomes the DR for the LAN segment that all non-DRs can form an adjacency
with? It should be no-one. In that case, R2 and R3 will not form an
adjacency and no routing will occur between them.
