Packet Tracer homework problem

Threaded View
I've just started the second half of my CCENT course, and we're just
learning how to configure routers using the CLI.

Our homework problem is:

End devices-----Switch------(Fa 0/1)  Router 1 (Fa 0/0) ---------- (Fa
0/1) Router 2 (Fa 0/0)--------Switch-----end devices



Each router has a switch and 3 end devices.
The problem gives all the IP addresses and masks to configure.

From the end devices within Router 1's network, I can ping local
devices, as well as Fa 0/1 (which is my gateway, right?) and Fa 0/0. I
can't ping beyond that.  Similarly, Router 2's network behaves the
same way.

So basically the routers aren't seeing each other.
I feel like I'm missing something very simple, but I can't figure out
what.

I've quadruple checked all my addresses.


I could use a hint....thanks for reading this far.

The topology is actually given to us, and it uses a crossover, no
serial.

What about the routing table?  Am I supposed to "tell" each router
about the other router?

Thanks for answering!

yes depends enable rip version 2
then type in each network address on each router
both serial address's on each router

Ehm, it should work with a ethernet link, serial link isn't required.

What you think isn't important.
You *MUST* set clock rate *ONLY* on DCE equipment.

You have to study a lot before reply again.

What you miss is posting the configuration of both routers.

Please login in on each of routers, type "show running-config",
copy and paste the configurations.

My professor posted some help for us online.

There qwere 2 commands we haven't learned yet, and these commands made
it work.

router eigrp 154
no auto-summary

No idea what these do, but I'm off to find out now.

The routers are seeing each other because they share the same network.
But each of them doesn't know about the network behind the other one.

That's why you need to enable a routing protocol.

router eigrp 154 ...  enables Enhanced Interior Routing Protocol on
your routers. 154 is process id or autonomous system. On every router
you must enable eigrp with the same process id. The routing protocol
allows router to advertise its directed connected networks to the
other routers on the network. So R1 will learn about the network
behind R2 through EIGRP.

no auto-summary ... disable automatic summarization.
