PLEASE HELP ME

topu

Hi,

I bought two 2501 router one 2900 switch and two pc with windows xp to make my ccna lab. Now I am struggling more then a month to build my home network.
I have connected my HosA(ip address 192.168.11.3/24) to the switch with ethernet cable. The switch (vlan1 interface 192.168.11.2/24 default gateway 192.168.11.1/24) is connected to RouterA with a ehternet connection(ip add 192.168.11.1/24) and RouterA connected to RouterB with Serial0 interface (ip add 192.168.22.6/24). HostB (ip add 192.168.33.2/24) connected to RouterB with ethernet interface (ip add 192.168.33.1).

My problem is I cant ping my default gate and router from hostA. All I can do just telnet my Swtich. could you please tell me why cant I ping my routerA and the default gateway from hostA.

any help will be appriciated.....

thanks

Your default gateway is router A, not the switch VLAN interface.

topu

thanks for your advice. That means I need to give an IP address for router itself. I thought I can use interface ip address as a default gatway address. If I have to give an IP address for Router could you please advice me how can I do that. I know how to configure ip address for Interface but not router itself. I know I am sounding like a stupid, I am a bigginer, I am reall sorry to be a stupid....

thanks

You need to give an IP to the interface on the router, not the router itself. Here are the commands to do so:

Router> enable
Router# configure terminal
Router(config)# int Fa0/0
Router(config-if)# ip address 192.168.11.1 255.255.255.0
Router(config-if)# no shut

This might not be of any help to you because you already listed this IP as being on the router, so you might've already done this.

Can you ping 192.168.11.1 from the switch?

Make sure your cables are the right types.

PC to switch: straight through
Switch to router: straight through
PC to router: crossover
Switch to switch: crossover

Try one router-switch-pc set first. Your 192.168.11.0 addresses are fine. Make sure at the router under the Ethernet interface you have ip address 192.168.11.1 255.255.255.0 and no shutdown or ip access-group ...

At the switch, for now, turn both the PC and the router ports into switchport mode access and spanning-tree portfast. If you can ping the router from the switch now, then you should be able to ping from the PC. Otherwise, try posting the router and switch configs here.

thanks for your help. one part of my network working fine but other is not working at all. I have connected my HostA to switch and switch to RouterA, this part of network is working good. But the problem is other side where HostB connected to routerB through a Ethernet cable is not working. could you please tell me the possible reason for it.I have configure IP address and RIP2 in the routerB but still network is down on hostB.

(I don't know how much you know, so I'll assume the least.)

How exactly is network down on hostB? In "Network Connections" in Windows on hostB, does it say "Connected" or "Disconnected"? If disconnected then you probably don't have a crossover cable between the PC and the router (see my last post on when to use crossover). Go to a store where they sell Category 5 (Ethernet) cables, and find one that says "crossover" on the packaging.

If cabling is not the problem, please describe the "symptoms" on hostB a bit more. Good luck.

topu

When I am doing, show IP interface brief its showing me connection is up but protocol is down. That mean my cables are connected fine but the problem with my logical lable, i mean protocol. could you please tell me what could be the reasons for protocol down. as I mentioned, I have configured RIP2 in router.

Do you have a link light on the router and the PC? If it's a serial interface, are you using a DCE to DTE cable? Is it install correctly (they can be plugged in upside down), did you set a clock rate?

/usr

Please don't take this the wrong way...but if you can't build a simple lab setup like this, you need to practice it on your own until you do.

You will understand it much better if you figure out why your lab isn't working properly, as opposed to having folks tell you have to setup one properly.

Just my 2 cents.

It was good advice actually.

I seriously hope you figure it out soon enough, but it is way better to understand why your network wasn't working before and you still haven't said you think it is working now. So stop being ignorant, and listen to the man.
