Hello
I have 2 cisco 2501 routers, (1E and 2S ports)
I have attached each ethernet to a different part of the LAN
I have put a db60-db60 cable on the S1 ports of both routers
10.0.x.x network SwitchA--ethernet--RouterB <-Serial-> RouterA - SwitchB 10.2.x.x network
I have looked it up in my CCNP BCRAN book but i don`t get the setup started
The setup for both connections are basic from a fresh install

Hi There
I am not sure I understand what the problem is or what you are asking. Is it a problem routing from the 10.0.x.x network to the 10.2.x.x network?
Best Regards,
Michael

Hi
Kindly tell your problem in detail.
Actually,your mail is not clearifying your problem.

I have a DB-60 serial cable between 2x Cisco 2501
Ethernet routerA is 10.0.0.0/16 network
Ethernet RouterB is 10.2.0.0/16 network
I want to establish a connection between these 2, but i get the message that the link is DOWN, while the config says the line should be up (without any configuration)

Hi Ramoonus,
I am not very clear what is the issue or our objectives of this lab.
As per my understanding you have 2 routers (model c2501). Say A and B.
On the Ethernet of router A you have 10.0.0.0/16 network and on Ethernet of Router B you have 10.2.0.0/16 network. Bother the router are connected by a Serial link using db60 cable.
You objective (I think) are to establish connecting between the two Ethernets subnet that is 10.0.0.0/16 and 10.2.0.0/16.
If so then here is the solution.
1) You need to assign IP address in the serial interface of both routers.
2) Configure routing on both the routers (either static or dynamic).
For point ONE command is
On router A
On the serial interface mode
IP address 192.168.1.1 255.255.255.0
No shut
Exit
On router B
On the serial interface mode
IP address 192.168.1.2 255.255.255.0
No shut
Exit
For second (static)
On router A (this is static default route)
In the configuration mode
IP route 0.0.0.0 0.0.0.0 192.168.1.2
On router B
In the configuration mode
IP route 0.0.0.0 0.0.0.0 192.168.1.1
Dynamic
On router A
In the configuration mode
Ip classless
Router rip
Network 10.0.0.0
Network 192.168.1.0
Version 2
Exit
On router B
In the configuration mode
Ip classless
Router rip
Network 10.2.0.0
Network 192.168.1.0
Version 2
Exit
Do rate the solution if it works

Hi Ramoonus,
There is a mis-configuration
Command ip address 10.2.0.1 255.0.0.0 mean that your network is 10.0.0.0/8 a class network. I think the command should be ip address 10.2.0.1 255.255.0.0 only then your network will be 10.2.0.0/16
