Stuck on on one of my practice labs

Hi all,
I'm doing Lammle's bonus labs Practice #2. This is the topology:
The IP addresses I'm assigned to work with are 192.168.10.0
I've assigned IPs to all the routers and to PC1. I've enabled EIGRP using Autonomous System "1". To the Routers p1r1 & p1r2 I did:
Next I'm supposed to verify connectivity to TFTP server from PC1. However, I can't ping further than the FA Ethernet Port that is connected to the switch, let alone to the TFTP server. I've tried pinging from the other routers to the TFTP server and not having any luck either. Can anyone steer me in the right direction?
Thanks!

What routing protocol are you using? Are adjacencies formed? Are routes being exchanged?An expert is a man who has made all the mistakes which can be made. -

I just went back and redid that lab because I'm also studying for ICND2. Did you do no auto summary?

I'd need to see what the routing tables and show ip eigrp neighbors look like before passing opinion. If you could post more of the configs that would be helpful. Other things to check Are your hosts able to ping the default gateway? have you run traceroute? have you ensured ports are in up/up state?I'm an Xpert at nothing apart from remembering useless information that nobody else cares about. -

Why are you not adding the Core Router to the EIGRP AS? -

Sorry for the late response guys, I didn't get notification that anybody respondedI just went back and redid that lab because I'm also studying for ICND2. Did you do no auto summary?
I did not do "no auto summary" until today and it still does not workI'd need to see what the routing tables and show ip eigrp neighbors look like before passing opinion.

Show IP Route:Core(config)#do show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is not set 10.0.0.0/24 is subnetted, 1 subnets C 10.10.10.0 is directly connected, FastEthernet0/0

1. I'm able to ping the gateway
2. I've run traceroute and it doesn't seem to work
3. I've now checked the ports and the serial ports all seem to be up/down - why is that? -

if all the serial ports are listed up/down could it have something to do with dce/dte and the clock rates? -

could you post your ip addressing scheme? just by looking at your core router i can see that there hasnt been any adjacencies formed with the others which prohibiting communication.
also have you turned off auto summary for the other two routers. im gonna try doing the lab myself to see if i can help you a bit more brah -

I have turned off auto summary on all 3 routers.
IP Addressing:TFTP Server - 10.10.10.254 Core Router FA 0/0 10.10.10.1/24 Core Router Se 0/0 192.168.10.1/30 P1R1 Router Se 0/2 (Connected to Core Router) 192.168.10.2/30 P1R1 Router Se 0/0 (Connected to P1R2) 192.168.10.5/30 P1R1 Router FA 0/0 (Connected to Switch 0) 192.168.10.25/29 P1R2 Router Se 0/0/0 (Connected to P1R1 Router) 192.168.10.6/30 P1R2 Router Fa 0/0 (Connected to P1S1 Switch) 192.168.10.9/29 P1R2 Router Fa 0/1 (Connected to Laptop) 192.168.10.17/29 PC1 - 192.168.10.14/29 with default Gateway of 192.168.10.9
Will it make it easier if I attach the Packet Tracer File? -

Auto summary or not, it's not going to work if your links are down. What have you tried there?An expert is a man who has made all the mistakes which can be made.

ok I'm reading online that's probably an encapsulation problem....don't REALLY yet know what to do with that though -

You have to learn to crawl before you can walk. First step is getting the link up. Some things to check are encapsulation type and clocking.An expert is a man who has made all the mistakes which can be made.

thats what it looks like to me too. The 'down' is the Layer2 aspect, and with a basic WAN setup on these labs there's no need to change or input any encapsulation type.
OP, double check your routers, all of them. Use the show controllers command and look for several things:
1) The first few lines will show you whether its DTE or DCE. If the former, move to #2. If the latter, issue the clock rate under that interface if it is not already
2) Ensure the encapsulation matches the other end of the serial link (HDLC, PPP, etc...). Again, with these labs the focus is not on WAN connectivity and troubleshooting, so the default encapsulation should suffice.
Anyways, just my opinion

If you post the Packet Tracer file it will be easier. On your core router you are not advertizing your 10 network.

Add a clock rate on the serial interface on the core router and p1r1 s0/0 interface. Setup the DHCP server for the DHCP laptops because they have no IP address. You can remove the 10 network from p1r2 router there is no 10 network on that router.

I love this lab. You have clocking issues (show controllers s0/x), encapsulation issues, and routing protocol misconfigured. Perfect lab! Todd Lammle -

Bingo!
The man himself has spoken. haha Awesome!
To OP, always test your serial links, without that your adjacencies will never form.Modularity and Design Simplicity:
Think of the 2:00 a.m. test—if you were awakened in the
middle of the night because of a network problem and had to figure out the
traffic flows in your network while you were half asleep, could you do it?
