Sam,
Did you add the "nei X database-filter all out" on R2 towards R3? If that's the case, I think that R3 does not have a route to R1's Ethernet address. So, R1 would have the route to R3's Lo0 but R3 would not know how to route back to R1.

Yes. R3's Lo0 was intsalled on R1's routing table.
R3 does not have R1's or R2's Lo0 routes. When I do a Sh ip ospf nei detail,
the lsa's are filtered.
Trying to get R1 to Ping R3's Lo0 & Vice-Versa, spent quite sometime on it.
No Luck So far.
Thx,
Sam.
