Help Setting Up Router to Router

PawNtheSandman

I have 2x 2610 routers. They do not have serial cards.

I wanted to hook them up together.

I have my PC going to Router A via the console cable. Router A is hooked up to Router B in the Ethernet ports via crossover cable.

I set up the ethernet0/0 interfaces on each router to have a unique IP

Router A: 172.16.12.1/24
Router B: 172.16.11.1/24

Both routers ethernet interface is shown as up, but while in HyperTerminal, I cannot ping from one router to another.

When I do a show cdp neighbors, they have the other router listed.

What am I doing wrong?

The routers are on different networks. You can change the address of one or both, or add secondary addresses to them so that they are on the same network.

CDP is a Layer 2 protocol. That shows the ethernet is working.

Put both interfaces on the same network such as 172.16.11.1 and 172.16.11.2 /24

just a question a little of the topic, is it common for routers not to include
serial interfaces...?

The 2500 series has built-in serial interfaces, but the 2600 series is modular, which means that the serial WIC cards can be easily swapped in and out. It is common to see the modular routers without a serial interface - which is why it is important to look at the specs before purchasing.
