I am have a little trouble setting up my home lab. I have a 3620 with two ethernet ports and a 3640 with four ethernet ports. I also have a 3500XL switch that I am using to connect the two together, but I can't seem to get each one to ping. Please help:
Here are my configs:

What you describe in your most recent post does not match what is in the configuration that you posted. And I am not sure which is correct.
If the config is correct then I understand your problem. In the config that you posted both port 15 and port 33 are in the default VLAN of VLAN 1. In this case when you connect Eth0/1 you have both router ports in the same VLAN and a layer 2 loop is created. If the config is not correct then perhaps you can post the correct config?

There are some things that you have not told us which might be part of the problem, such as which switch ports connect to the routers. So a more complete explanation of the topology of the network might be helpful.
But I do see a problem which would prevent the routers being able to communicate with each other. There is no subnet in common. I am assuming that your intention is to connect Eth0/1 on the 3620 to Eth1/0 on the 3640. But their IP addresses are in different subnets. 10.0.1.10 is in subnet 10.0.1.8 while 10.0.1.13 is in subnet 10.0.1.12. The easy fix would be to change the subnet mask on the interfaces to make it a larger subnet which would include both addresses.

3620 is connected to swithport 1 and 3640 is switchport 15. Once I change the ip address to be on the same subnet, I will be able to ping throughout the entire network, correct
03-29-2012 08:28 AM
Jonathan,
Little more explanation requied on the topology.
What port of 3620 and 3640 are connected to swithport 1 and 15 respectively??
-Vijay
03-29-2012 02:56 PM
3620 - Ethernet 0/1 to 3500XL Switch Port 0/1
3640 - Ethernet 1/0 t0 3500XL Switch Port 0/15
I also have a 3745 connected via serial connection to the 3640 that works just fine. Once we get the 3620 connected to the 3640 will the 3620 be able to "talk" to the 3745?
Also, normal straight through cables is all I need, or do I need crossover or any other ethernet cable?
03-29-2012 07:15 PM
3620 - Ethernet 0/1 to 3500XL Switch Port 0/1
3640 - Ethernet 1/0 t0 3500XL Switch Port 0/15

switch ports 0/1 and 0/15 are both in vlan 500. So once you straighten out the subnet masking so that the 3620 and the 3640 are in the same subnet then they should communicate with each other.
There is at least one problem that will prevent the 3620 from communicating with the 3745. The configuration of EIGRP on the 3620 has 2 network statements. They are for 192.168.0.0 and 192.168.2.0. But neither of these are networks in the interface configuration. And there is no network statement for 10.0.0.0 so EIGRP will not run on interface Ethernet0/1. And without EIGRP running on that interface the 3620 will not have a route to get to the 3745. If you add a network statement for 10.0.0.0 (and assuming that the 3745 is participating in EIGRP) then I think that the 3620 should be able to talk to the 3745.

Ok, looks like I am going to need some help with the subnets (this is just a home lab, so if we have to change them all, I am fine with that).
I still can't ping anything from my 3620 router...Below are all my running configs:

You have made quite a few changes but still do not seem to understand how the subnets work. Is the 3620 still connected to the 3640 Ether0/1 to switch and switch to Ether1/0? Or has that connection changed?
Assuming that this is the connection change the subnet mask from 255.255.255.252 to 255.255.255.0. This is not the only mask that would work, but it is the easiest and most simple fix. When you change the mask these routers should communicate with each other.
If the 3745 connects using its serial0/0 to the 3640 serial 0/0 then I would think that they can communicate with each other. Is that the case? If the connection from the 3745 is serial 0/1 then it would be a problem. Can you clarify which one it is and whether it works.
There is another problem which prevents the 3620 from communicating with the 3745. One aspect of the problem is that you have configured static default route on both routers with a next hop of 192.168.2.1. But do these routers know how to get to 192.168.2.1? If you do show ip route 192.168.2.0 on either router do they have a route? I do not think that they do.
The other part of the problem with routing is the configuration of EIGRP. Both the 3620 and the 3640 have network statements under EIGRP for 192.168.0.0 and for 10.0.0.0. But they do not have any interfaces in those networks. And the interfaces that they do have do not have network statements under EIGRP. Note that 192.168.3.0 is a very different network from 192.168.0.0. So if you put a network statement for 192.168.3.0 under both router's EIGRP then they should exchange routes.

Sorry, didn't mean to make the changes, I thought I had it figured out but I didn't.... here is what is connected to what...
3620 connected to 3500XL Switch F0/1 -----> E0/0 192.168.3.1 255.255.255.252
3640 connected to 3500XL Switch F0/16 -----> E1/0 192.168.3.2 255.255.255.252
3640 serial 0/0 10.0.1.10 255.255.255.252 ----> 3745 serial 10.0.1.9 255.255.255.252
From the 3640 to the 3745 connection is good, I am able to ping 192.168.2.1 (3745 F0/1) and 10.0.1.9 (3745 S0/0)
Could you help with the config, so that the 3620 and 3640 communicate and can talk to the 3745 as well...Like I stated before this is just a home lab, so no big deal if I need to change configs completely. What should the 3620 and 3640 config look like just so that they communicate?
Thanks?

Ok, I figured it out...but one last issue...I am able to talke to each router, but when I enable e0/1 I loose connection. Why?
Here is what I have:
3620:
E0/0 192.168.3.6 255.255.255.252 ------> connected to switch port 33/vlan 500
E0/1 192.168.4.1 255.255.255.0 ------->what this it be the DHCP server pool ---->connected to switchport 15 vlan 300
3640:
S0/0 10.0.1.10 255.255.255.248
E1/0 192.168.3.5 255.255.255.252 -------> connected to switchport 16/vlan 500
3745:
S0/0 10.0.1.9 255.255.255.248
S0/1 10.0.1.5 255.255.255.248
F0/0 DHCP via ISP
F0/1 192.168.2.1.255.255.255.0
EIGRP 1: ----> set on all routers
network 10.0.0.0
network 192.168.2.0
network 192.168.3.0
network 192.168.4.0
Switch:
Ports 1 and 15 are vlan 300
Ports 16 and 33 are vlan 500
Wireless AP connected to switchport 15/vlan 300 to pull from the 192.168.4.0 DHCP pool

What you describe in your most recent post does not match what is in the configuration that you posted. And I am not sure which is correct.
If the config is correct then I understand your problem. In the config that you posted both port 15 and port 33 are in the default VLAN of VLAN 1. In this case when you connect Eth0/1 you have both router ports in the same VLAN and a layer 2 loop is created. If the config is not correct then perhaps you can post the correct config?

your router interfaces are in diferent subnetworks:
ip address 192.168.3.1 255.255.255.0 vs ip address 192.168.1.1 255.255.255.0
ip address 10.0.1.10 255.255.255.252 vs ip address 10.0.1.13 255.255.255.252

Figured it out...my subnetting was way off....thanks for the help and guidance. Still learning...
