"OPSF Hub-And-Spoke And Virtual Links" lab - Issue Resolved

In response to yesterday's post: here
I have resolved the issue.

NOTE: Unused interfaces and other portions of the config are omitted.

Ok, so I went back to basics borrowing from this config, I configured R4 and R5 based off of:

http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a0080094057.shtml#conf1

Modified Configs:
Router 4

host R4
!
interface Loopback0
ip address 4.4.4.4 255.255.255.255
!
interface Serial0/1
ip address 1.1.1.4 255.255.255.0
clock rate 64000
!
router ospf 1
network 1.1.1.0 0.0.0.255 area 0

Router 5

host R5
!
interface Loopback0
ip address 5.5.5.5 255.255.255.255
!
interface Serial0/1
ip address 1.1.1.5 255.255.255.0
!
router ospf 1
network 1.1.1.0 0.0.0.255 area 0

Here, the main difference is that I used HDLC between R4 and R5 versus Frame-Relay. I am able to establish an adjacency between
the two:

=================================================================================

I reconfigured R4 and R5 to reflect HDLC along with the lab book's info:

The adjacency is established:

R5#

And thanks to the virtual link, I can now ping back to the hub router (R1).

R5#p 1.1.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 92/93/96 ms
R5#

R5#sh ip ro os

O IA 1.1.1.1 [110/846] via 10.2.2.4, 00:03:03, Serial0/1

O 172.12.123.0 [110/845] via 10.2.2.4, 00:03:03, Serial0/1
R5#

Now, I know Frame-Relay point-to-point is possible. This link proves it:
http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a0080094054.shtml#conf

I think my mistake with Frame-Relay OSPF Point-to-Point is that I should have
established a point-to-point sub-interface, e.g. interface Serial0.1 point-to-point
versus making R4 a frame-switch just to deal with point-to-point connectivity between
R4 and R5. O_o ??

Could be another reason, but I got frame-relay p2p to work as well. Check it out below:

Labs - Bryant Advantage

Completed the first three labs for BSCI (Layer 2, Static, RIP). Nice explanations. Gives you a better feel for doing labs without an "answer key," as a typical CCNP/CCNA lab would have. I'll do more of these tonight if I'm not too tired, then start EIGRP (Doyle, notes, lab) tomorrow.

Lab Challenges

Where were blogs like these in 2000? Here's a couple of lab challenges from Just another CCIE
CCIE #20728. Pretty nice, and also free! So go ahead, lab it up!

IPv6

Worked through most of IPv6 in Doyle's Routing TCP/IP. That's a great book! Took thorough notes, will finish tomorrow morning and move on to RIPv2 (finally), then on to EIGRP. Hopefully I can get some time in to work on my lab before the week is out. Plan to run through those RIP labs from the Bryant Advantage and Mohamed Ouamer. These are just basic labs, but I'm doing them to reinforce concepts as I progress. I plan to continue on that route building up my understanding for the Written, and at the same time, preparing for transition to Soup-to-Nuts (S2N) once I have completed the written. I plan to take the written by the end of November, beginning of December before this project at work ramps to full speed. Anyway, that's the basic gist of my plan. I'll place a real outline later.

TCP/IP/VLSM/Summarization/CIDR

Well, never made it to RIPv2 : (. Spent the day taking thorough notes on TCP/IP/VLSM/Summarization/CIDR. Read the first three sections of the Bryant Advantage BSCI Study Guide: IP Routing, DV Routing, & VLSM, Summarization, and CIDR. Will go back through to make flash cards for reminders. Will follow up with IPv6 from Routing TCP/IP Volume I, either tonight and tomorrow, or just tomorrow.

Free Labs

Looks like a new site is up by Mohamed Ouamer. I'll run through a few of his labs and post my thoughts afterward. It actually could be a good find as I am spending the day running through RIP, and he has several RIP labs up.

Cisco Doc CD + Tutorial

http://www.cisco.com/univercd/home/home.htm

When I run into trouble on my labs, I use the DOC CD, which I am getting better at using, thanks to the Internetwork Experts tutorial:

How's that for an endorsement... j/k
