Hi all,
This question has already been posted but it's not discussed thoroughly, so I re-post it
It seems to me that the correct answer will be "RT2 will obtain a full routing table, including a default route, from RT1".

I've already simulated the question on the lab and the correct one is as above.

Extract configuration on RT1:

router ospf 1
log-adjacency-changes
network 172.16.100.0 0.0.0.3 area 0
network 172.16.100.64 0.0.0.63 area 0
default-information originate
!
ip route 0.0.0.0 0.0.0.0 Serial0/0
!

------------

routing table on RT2
RT2#sh ip route

    172.16.0.0/16 is variably subnetted, 3 subnets, 3 masks
O      172.16.100.64/26 [110/65] via 172.16.100.1, 00:02:13, Serial0/0
C      172.16.32.0/22 is directly connected, FastEthernet1/0
C      172.16.100.0/30 is directly connected, Serial0/0
O*E2 0.0.0.0/0 [110/1] via 172.16.100.1, 00:02:13, Serial0/0
RT2#

-------------------
Routing table in RT2 includes default route advertised from RT1 through OSPF.
Looking further into the OSPF database table on RT2 for default route:

RT2#sh ip ospf database external

            OSPF Router with ID (3.3.3.3) (Process ID 1)

                Type-5 AS External Link States

  Routing Bit Set on this LSA
  LS age: 497
  Options: (No TOS-capability, DC)
  LS Type: AS External Link
  Link State ID: 0.0.0.0 (External Network Number )
  Advertising Router: 2.2.2.2
  LS Seq Number: 80000001
  Checksum: 0xFEAB
  Length: 36
  Network Mask: /0
        Metric Type: 2 (Larger than any link state path)
        TOS: 0
        Metric: 1
        Forward Address: 0.0.0.
        External Route Tag: 1


Which means the default route from RT1 didn't include next hop in its LSA, thus RT2 has no idea
if there will be a loop if it put default route in its routing table.

Would anybody advice?

Thanks,
Peter

I am preparing to take the CCNA exam 640-802 and was wondering if anyone can recommend a good testing center in LA or Orange County.  Thanks!

hi there,

i'm not getting this, i understand the nat of the source IP from inside local to in side global but
should the outside local not be the 172.16.1.254 ?? or is nat not done both ways Huh


cheers,
Caomhin

I cancelled my ccna exam 2 days ago. The date of the exam is 11/20/2010. But I am really very busy... I had reschedulled the exam for many times... so I cancelled it...
Could you tell me whether I can get a full refund? It said: 'refund: $250'.  I am not sure about it, because I haven't recieved the refund...

Thank you very much!

I'm not embarrassed to say that I have no idea what the Acronym QID stands for. I was trying to avoid your DUH! responses, but could someone enlighten me.
Thanks

Most of the questions were very similar to the H2P content. Highly recommended.

When do you think the CCNP Route thread will be active in addition to updates to the How2Pass content for that test?  (labs and questions)  As it stands right now even if I had the content down I would wait till the next update and till the thread is open to take the test.

Hello,
Show CDP Neighbors Detail is a command that is called out in the answer, but when attempting to duplicate in HQ router it does not work.  Using IE 7.0.5730.13 and Firefox 3.6.8 on windows XP Pro machine.  Please correct problem.
Thanks I appreciate these practice tools.

What is your biggest question about computer networking?

Are you concerned about achieving certification?
Is there some topic you want clarification about?
Do you want to know how to expand your knowledge?

It could be anything, even if you think it is silly.

Here is your chance to ask a CCIE.

Come to a free webinar this Thursday at 10PM EST / 7PM PST

Hello, 

745/1000

This is may second attempt to take the CCNA 802.  The only material I used was testout package and some brain dumps that didint really explain well.

I found this browsing the net and rapidly subscribed.  Now im planning to take the test for the third time in December 1st.

I have a question.

On the EIGRP Sim I found the mistake and corrected it but, still couldn't make adjacency.  I checked the interfaces and ips they seemed good.
On the ACL sim I got the router to only allow the one host access to the specified server and even tested it but, still only got 50% on the section.

Anyways How2pass seems very promising. If anyone can help with those I would highly appreciate it.

Regards,

Yass
