Two LANs Connected via T1 - cannot get them to recognize each other

Ok, here we go. I have a T1 line that is supposed to connect my LAN at my datacenter to my LAN here at the office. I have at the data center IP addreaa range of 10.2.0.1-255 here at the office it is a 10.0.0.1-255 network.

on each end is a cisco 1721 set.

router datacenter is configured as:
serial0:
ip address 10.1.0.1 255.255.255.0

router eigrp 1
network 10.0.0.0
auto-summary
!
fastethernet0
ip address 10.2.0.1 255.255.255.0
speed auto
half-duplex
no cdp enab

OK router main office is configured as:
serial0
ip address 10.1.0.2 255.255.255.0

router eigrp 1
network 10.0.0.0
auto-summary

fastethernet0
ip address 10.0.0.2 255.255.255.0
speed auto

this is what I have so far, but I am unable to see the computers from one end to another.

Thanks,
jeff,

so far config looks fine.

can you ping the datacenter-router from the office-router and vice versa ?

Jeff,
What does the show ip route say on each end?

1) You  need to turn OFF autosummary, since all the addresses are in the 10.x.x.x range, but you want to see the subnets.  (EIGRP auto-summarize on classful boundaries, so both routers think they own 10.x.x.x.x when autosummary is on)
2) if it still doesn't work, show ip eigrp neighbor to see if the routers are talking

Hi skipmurphy14,

The router configs look fine, as stated before. However have you checked that the line is actually up. You can verify this by running the following commands in privilege exec mode (i.e. once you have typed "enable" on the router):

show interface serial0

check that the output on the first line says:

Serial0 is up, line protocol is up

the important bits being the up/up status of the line protocol and interface. If the line protocol is down, check with your provider that everything is OK there end (also make sure that you are using the same encapsulation types at each end - if you have left everything as default then they will be set to HDLC).

If it says Serial0 administrativly down, then you need to do a "no shutdown" on the interface to bring it up (type "conf t", then "interface serial 0")

If everything is OK, then have you made sure that either the hosts default-gateway's are set to the respective routers interface, or alternativly a static route exists for the remote subnet?

Also check that you can ping the router ethernet interfaces from each site, this will confirm communication between host and gateway (and that they are on the same layer2 network (i.e. not on different vlans/switches etc....).

You might also want to verify that EIGRP is seeing each neighbor and that the routes are in the routing tables, these can be done by issuing a:

show ip eigrp neighbors
and
show ip route

(again in privilege exec mode)

you should see the other router as a neighbor, and the remote subnet as marked with a "D" in the routing table

If all the line's are up, and you see the neighbor, and the route is there. I would say it is a host problem....

Best of luck!

Jeff, I still say you need to turn off autosummary - I think j3ggs and I posted at about the same time, stepping on each other.

I also don't know if this helps but when I do a show ip route this is what I get

Gateway of last resort is not set

Jeff,

Assuming that you have issued a show ip route on the data-centre side, that static route should not be there (providing this is the only network connections you have).

Also, I dont think looking at that routing table, that what you have pasted on to this site is correct (as the line "C       10.2.0.0/16 is directly connected, FastEthernet0" show that it has a 16 bit mask, i.e. 255.255.0.0).

Anyway, if you look at it, what will happen is that traffic from the 10.0.0.0 network (main office) will route to the other site, but the data centre has a more specific route for the network 10.2.0.0/24 which is via your main site.

If you do a show run, you will have a line that says:

ip route 10.2.0.0 255.255.255.0 10.1.0.2

take it out by typing

conf t

no ip route 10.2.0.0 255.255.255.0 10.1.0.2

EIGRP will sort out the routes, as a static is more prefereable than any other (other than connected) it will over-ride the EIGRP route, which is why it is not in the table.

that should fix you.

regards

j3ggs


PS I would write the config first (write mem, or copy running-config startup-config), and be prepared that this MAY lose you connectivity, but by the looks of it you cant communicate to the other network anyway. Be prepared to re-boot the router if all goes wrong (which is why you should write the config first), and this will obviously cause an outage.

Well here it is with all that information that is on ee and your added suggestions, I am still only able to ping from router to router, but when I do a tracetr from each machine the packets are actually trrying to go out the public ports.  Meaning I have on the main office a router that shooots out to the internet and a router that is supposed to go to the other LAN.  On the datacnter side I have a line that goes to a bridge for our outside IP's, and a router for the main office location.  For some reason everytime I try to ping all routes try to go out the public routers.  Do you know what I have to do to get it to point to the private T1 router, and still have the outside addresses be public?

OK, a crude diagram.... Do you have the following setup (the "O" is a router):

I guess I should explain that a little.  each server at the datacenter has 2 nic cards, one has an outside IP and one has an inside IP.  each have their own switches.  and each has its own line out of the datacenter.

OK From the main office, can you ping the data centre router ethernet interface?

i.e. can you ping 10.2.0.1?

If this is the case, you have an issue on your servers, possibly that they have 1 default-gateway that points out to MCI. If this is true then you will need to add a static route to the servers/hosts in the data-centre pointing to 10.0.0.0 /24 (i.e. on a Windows box, type: "route add -p 10.0.0.0 mask 255.255.255.0 10.2.0.1) - you may have to add metric and interface commands.

If you cannot ping the router interface then we still have a routing problem (plus we may have to look at the above comment as well). Can we get the results of a "show ip route" and a "show ip interface brief" from each router? (and please state which router the command came from.

Many thanks

This is alos kinda wierd, when I configured the routers, it looks as if it is online because a bunch of the internal NICs get confused when the line is up.  We have a vpn that users use now to get into the datacenter (this private t1 will take the place of it).  So we are thinking that the inside nics get confused because it sees a whole bunch of IP addresses twice.

j3ggsCommented:
Are you using a VPN client or an appliance that would be injecting routes? If you are using clients. then it should work if you do not have the client software running (i.e. have now VPN up).

As long as the gateways/routes are correct on the servers at the data-centre, and the users are not using a piece of client software then you should still be able to communicate to the servers......

Is something else putting routes in to your routers routing tables? Is it possible to get the output of those show commands when everything is up (i.e. the leased line).?

Jeff,

(1) give us the router configs as they are now.
No need to change anything before giving the configs.
But please give the complete configs, at least for all of the interfaces and routing.

(2) Then, tell us what the behavior of the network is with those some configs.
Reading the numerous posts, it sounds like the network behaves normally with the current configs. Is that correct?

(3) What precisely do you mean when you say that the internal NICs get "confused"?
To help explain that, here is a suggestion: pick one server that is "confused", and while it is in that state capture the ip configuration and post it here (on most Windoze you can use "ipconfig /all" in a dos window).

Jeff,

If the info in the first post is correct and you haven't got the configs the wrong way round, the static routes on each router are wrong.

Here is my diagram with IP's


Datacentre                                                   Main Office

10.2.0.0/24--------O-------10.1.0.0/24-------O------10.0.0.0/24

Therefore on your datacentre router you should have a route that points to 10.0.0.0/24 via 10.1.0.2

On your main office router you should have a route that points to 10.2.0.0/24 via 10.1.0.1

From your routing tables these routes are the opposite way around, causing a routing loop. Are the original configs correct in the 1st post? I say this again becuase the connected route on the datacentre routers says that the mask on Fastethernet0 is 255.255.0.0

Please note that when your routes are sorted, you still need to get the hosts with dual nics talking. I would get to the point to where you can ping the routers ethernet interface (from main office to data centre) and then move on to host-to-host connectivity.

regards

j3ggs

PS Can you ping the datacentre's serial interface from the main office?

j3ggsCommented:
you posted while I was typing... ok my theory was correct, your routes are all wrong (they point straight back to the other sites).

in response to your pinging the other site and it trying to go out via the internet, do you have a default-gateway, is it your firewall or another router on your lan? If so, you either need to put a route in to this device as well to make it route traffic via your main office router (i.e. the one we are talking about), OR put a static on your host PC (I would do static on the host for now to test).

Jeff,
I agree with j3ggs that the static routes are wrong, and need to be pointed the other way.
Delete ALL the static routes on both routers and then put in one new static route on each, pointing as he said:

Datacenter:
ip route 10.0.0.0    255.255.255.0    10.1.0.1

Main office:
ip route 10.2.0.0   255.255.255.0    10.1.0.2

here is a stupid question, how do i go about deleting the other routes?  Is it delete ip route yada yada yada?

j3ggsCommented:
go into global config (i.e. conf t) then type "no ip route 10......"

for instance

conf t
no ip route 10.0.0.0 255.255.255.0 10.1.0.1

the way I remove multiple entries is to paste the original statements in to notepad, then put a "no" in front of each, and paste the whole lot back under global config.... this way there are no typo's etc!

Guys,

Datacenter:
ip route 10.0.0.0    255.255.255.0    10.1.0.1

Main office:
ip route 10.2.0.0   255.255.255.0    10.1.0.2

this doesn't work.  when I input the ip route on the datacenter it says

Invalid next hop address (it's this router)

should I swap the 10.1.0.1 and 10.1.0.2?

j3ggsCommented:
Yep,

the route should be:

Datacentre:
ip route 10.0.0.0 255.255.255.0 10.1.0.2

Main office
ip route 10.2.0.0 255.255.255.0 10.1.0.1

IP route at main office

Gateway of last resort is not set

     10.0.0.0/8 is variably subnetted, 4 subnets, 4 masks
S       10.2.0.0/24 [1/0] via 10.1.0.1
C       10.1.0.1/32 is directly connected, Serial0
C       10.0.0.0/16 is directly connected, FastEthernet0
C       10.1.0.0/30 is directly connected, Serial0

Also when still trying to tracert from actual machine, its still trying to ping out the other routers on both ends.  What was that thing you guys were telling me about routing in windows?

Great, so your almost done.... Not sure of your internal network structure, but to proove you have end to end connectivity you could add a static route on your PC and a server in the data centre.

For instance, on your PC (in the main office) you would put:

route add 10.2.0.0 mask 255.255.255.0 10.0.0.3

and on the server/host in the data centre you would put:

route add 10.0.0.0 mask 255.255.255.0 10.2.0.1

Thats assuming that both devices are microsoft boxes. Then (as long as there are no firewalls active) you should be able to ping across.

Moving forward, you would need to put a route on your default gateway (say that was 10.0.0.1) pointing to 10.2.0.0/24 via 10.0.0.3, then there will be no need for statics on the workstations in the main office.

In the other site, as the boxes have dual NIC's you may have to stick with statics?

Jeff, are there more than 200 computers on either end (datacenter or office)?

And, do yo have a DHCP server on either side?
