Hi David,
don't know exactly, but by configuring the virtual link, R1 turns into an
ABR, and it will ignore the summary LSA originated by R3 for area 0 within
area 2 as it knows all about area 0 himself.
To make OSPF to IGRP redistribution work, you'd need to configure the same
summary (area 0 range ..) on R1 as well..
