EIGRP - RIP Redistribution

[Titan]

Hi There,
first I have to say sorry about my English language skill. I hope you dont
mind.
I have configured my network on Cisco Packet Tracer and I have a problem with EIGRP and RIP redistribution. In the routing table of CORP I have the "D EX" advertised route with AD 170 to the remote network 10.1.12.0. But in the book, on page 433 I see "D" with AD 90. Can anybody tell me where is the mistake in my configuration?
Another thing... R3 configuration... "redistribute rip metric 10000000 20 255 1 1500". I had set up the value of delay with 20000, but when I check the running config, I see 2000 only. Then I checked it time to time, and it was 200 and now is 20. How can it possible?
I hope... someone has the instant solution.
Thanks for your helpfulness
