I like you Herbert. You took your first knock and you got right back on your
horse... me too man!

Do you know what the difference is between a CCIE that passed on the first
attempt and one that passed on the 5th attempt?

Nothing... they both make $300,000 a year as consultants once they learn to
sell themselves properly at $150/hr

Perhaps you should show the OSPF database on R5 to confirm that you are
receiving these routes from both R4 and R3, then we take it from there to
see why they are not being installed in the routing table.

Keep in mind that OSPF performs only equal cost Load Balancing.
