Point to Point

edgarver1

I have 2 new T1 circiuts installed for a point to point connection between two offices. I have not worked with a cisco router in quite some time.

The topology I have now:

Office 1 network = 192.168.100.0

Office 2 network = 192.168.200.0

2*T1 = 3.0Mbps Point to Point

Here is my current configuration that I have setup so far:

Office one

Fast Ethernet0/0 IP = 192.168.100.250

Serial0/0/0 Unassigned

Serial0/10/ Unassigned

IP default-network 192.168.100.0

Office 2

Fast Ethernet0/0 IP = 192.168.200.250

Serial0/0/0 Unassigned

Serial0/10/ Unassigned

IP default-network 192.168.200.0

IP Route

I added this routing:

Ip Route 192.168.200.0 255.255.255.0 192.168.200.250

IP Route 0.0.0.0 0.0.0.0 192.168.200.250

If I run command 'show ip route' I get this: "Gateway of last resort is not set"

What are the steps I should take to get this point to point operational ultilizing the 3.0Mbps for it.

OK I have removed the PPP Authentication Chap on all serial interfaces. However this did not bring up the serial or multilink1 connections. I also removed the routes I added earlier to see if that would do it and that did not work. Now one thing that came to my mind, since this is a private line connection, don't I need to designate clocking on one of my routers?

It is quite possible that you do need to designate clocking on one of the routers. If the provider is not providing clocking, and you do not designate clocking then it would cause a problem. But the symptoms would be slightly different. If it were a clocking issue I would expect the interface status to be up/down. Your post indicates that the interfaces are down/down if I understand them correctly. In my experience down/down suggests a different problem, frequently it is a physical layer problem such as disconnected cable, faulty cable, powered off CSU/DSU, or something like that.

I do note that the show interface output that you posted indicates that the router has integrated CSU/DSU and I do not see any controller configuration or service module configuration. Configuring the CSU/DSU might be helpful in this issue.

OK, did loopback test on the CSU/DSU units and they are functioning correctly. Also was in contact with my service provider and the private line is working. However, I need to get the demarc extension verified so I will let you know. A cisco engineer says that the config should be fine so as soon as I get my indor cable verified and will let you know the outcome. I real appreciate all your help guys.
