Hardware setup

Ok i have 2-2611 routers that im using for my lab.
my other 3-2501's are on hold until i upgrade them.

but i was reading the techlab about hardware on the forums, and it uses an adapter v.35 male and female, to hook the routers to each other.

my question is , why could i just use a serial to serial connection, instead of serial to v.35 male to v.35 feamle back to serial.. would a serial to serial cable be easier.

also i tryin to ping my 2611 router. How exatly do i need to set it up to my comp for it to ping it.

do i use the ethernet port of the router and connect it to my NIC card. Or how???

also how would i hook up 2 of them, so i could ping both

OK my router has a ethernet port, not fast, so i believe the setting is 10mpbs, i set my nic card to auto detect on the mode( half/full duplex) and auto detect on speed.. line protocol still shows down????.. i also tried to set the NIC for 10mbps speed. But still the line protocol says down.

also my NIC IP address is DCHP, so when i hook it to the router it becomes 169.254.21.156, and the subnet mask 255.255.0.0 what are the valid subnets for this mask. i set m routers IP address to 169.254.21.160

should i manually configure my NIC ( i would have to change it back to access the internet though) (how can i statically assign an ip address for my NIC ( and access the internet)

If the protocol is down, the first thing I'd check is what someone already asked -- did you do the "no shut" command on the interface.

Do a show run and paste in the configuration of your Ethernet port.

You might as well include the output of a show interface command for your Ethernet port too.

This is a 2600, right?

Make sure the crossover cable you're using is in working order, and it may seem obvious, but the 2611 has 2 ethernet interfaces on it, make sure you're using the one marked Ethernet 0/0 (not 0/1)

Um.... you seem to have your router interface configured with an address that belongs to the Microsoft auto-net network range (169.254.0.0/16) -- rather than what you originally said you had.

Oops... just saw this --

So you fixed the "other problem" and are now trying to configure your router as a DHCP server?

Or do you have a switch now and a DHCP server?

What problem are we trying to solve now?

lildeezul

the problem were tryin to solve is why it wont PING

Do you IM? If you do, maybe one of us can walk you through some of the stuff...

I think you need to start from the beginning.
Make sure you have a crossover cable directly from your PC NIC to your routers ethernet port.
Then make sure your PC is set to a static IP of your choosing, i would suggest something simple like 1.0.0.1 255.255.255.0.

Then on your router configure your ethernet port (make sure it is the correct port)

Router>enable
Router>#conf t
Router>#(config)interface ethernet0/0
Router>#(config-if)ip address 1.0.0.2 255.255.255.0
Router>#(config-if)no shutdown

Then you should be set, do show interfaces to confirm that ethernet0/0 is up line protocol is up.

If line protocol remains down, look to make sure your cables are correct, and check for activity by looking at the lights.

OK i change the cables, and thanks god the line protocol change to state up. I assigned my router IP address 1.0.0.2 255.255.255.0 and my nic of my laptop 1.0.0.2 255.255.255.0 and still no ping. Am i using the wrong ip address ( non valid)

dtlokee

Did you appen to get an IP address conflict message when you did this? The addresses need to be different on both devices one could be 10.0.0.1 and the otehr 10.0.0.2

Netstudent

Two nodes can never have the same IP or overlapping subnets, unless there is a router between them performing NAT. Someone correct me if I'm wrong.

I ping succefully thanks guys.

I feel like an idiot becuase i just read about Cisco 4 ways to to trouble shoot an IP. i figured out my problem. my first problem was the actual phyical connection with the cable. once
i changed the cable the protocol changed to state up. After that my assigned ip addresses
were wrong. ( invalid) i change them to a class C address with a /27 subnet mask.
( 255.255.255.224) i put my computer and router ip on the 32 subnet, and assigned my
comp with a 192.168.0.33 ( since the valid host is 33-62) and my router address is 192.168.0.34
and i pinged my comp and it was successful. i'm so happy i figured it out. but i feel dumb lol.

now all need help is with connecting to the internet on a static IP address. With the assigned
computer Ip address i cannot access the internet, but when i changed it to " assign computer
address automatically" it works. How would i go about connecting the internet with my
assigned IP address, that way way i cant connect to my router and my internet without
changing Ip address. does anyone know?

do i need to go to my defualt gateway ( 192.168.0.1) and change my modems ( netgear)
configuration? if i do this will it effect other computers on my network?

In windows you have 2 ways:
You can get an IP address automatically, then discover your IP address on windows or your router/modem and then statically assign yourself that IP address.
Or you can do a secondary setup by using the alternate configuration in network connections>LAN connection>TCP/IP properties>alternate configuration tab.
