CCNA Lab equipment 1

[rdurant]

Hello All,

Just bought 2 x 2501 routers and a 1912 switch to start setting up my lab. First, are these 3 devices adequate? Secondly, what cables do I need to use with the devices?

1) your first problem is that you have one subnet for your entire network.

2) only connect one router to the switch

router 1 s0 connects to your 4500 s0, 192.168.1.x/24
router 2 s0 connects to your 4500 s1, 192.168.2.x/24
router 3 s0 connects to your 4500 s2, 192.168.3.x/24
any router's e0 connects to your switch, 192.168.4.x/24

don't forget, on the dce cable side you need to add the clock rate command.

Hang in there, it gets better

Jsteve,

the IP at the end, is that for the router or for the 4500 serial port?

 

[Jsteve]

Here is the commands if you don't know

DCE Side;
#enable
#config t
#int s0
#ip address 192.168.1.1 255.255.255.0
#clock rate 64000
#no shut
#exit
#ip routing
#router rip
#version 2

DTE side;
#enable
#config t
#int s0
#ip address 192.168.1.2 255.255.255.0
#no shut
#exit
#ip routing
#router rip
#version 2


Do the smae for your other networks and whah LA

DCE Side;
#enable
#config t
#int s1
#ip address 192.168.2.1 255.255.255.0
#clock rate 64000
#no shut
#exit
#ip routing
#router rip
#version 2

DTE side;
#enable
#config t
#int s0
#ip address 192.168.2.2 255.255.255.0
#no shut
#exit
#ip routing
#router rip
#version 2

If your talking about the /24, its a short cut for the net mask. it means 24 bits set to on = 255.255.255.0

 

[Jsteve]

I see what your asking.
Think of each cable as a seperate network, and at each end there is a diff address at each end on the same subnet.

so the 192.168.1.x/24 would be 192.168.1.1 on one end and 192.168.1.2 on the other end.

 

[techxupport]

Thanks for all the help Jsteve.

Now how about the router e0, do I have to do anything to them?
What about the switch problem that I have also. How come I can't see the router or switch?

Thanks again.

 

[techxupport]

oh another thing,

How do I test to see if its communcating between the routers.

 

[Jsteve]

Ping each address from one router.
i.e. ping 192.168.1.2

also take a look at the routing table.
show ip route

 

[techxupport]

I am doing this via console to 4500

I am trying to ping from the 4500 to 192.168.2.2
success rate 0

I am trying to ping from router 2 to 4500
success rate 0

another question I have is do I have to config an IP on the switch as well?

 

[Jsteve]

you dont need to config an ip on the switch now.

copy and paste a "show int s0" , so that I can take a look.
also paste a "show ip route"

[Jsteve]

post the 4500

 

[techxupport]

Post it.

 

[Jsteve]

ok,
on your 4500, change the encapsulation on all your serial interfaces back to HDLC

#int s0
#encap hdlc

also mack sure that the cable end that is marked DCE,you use the clock rate command.

 

[techxupport]

Bingo... That works!!!

JSteve is the MAN.

Thanks dude for this late hour support.

But for some reason I am still having problem with the switch can't see one of the routers.
Its not the tranceiver or cable cuz I switch them all around.

You've been a great help Jsteve.

 

[techxupport]

Okay just realize something.

I can ping from router 1 (192.168.1.2) to 4500 (192.168.1.1)
I can ping from 4500 (192.168.1.1) to router (192.168.1.2)
I can't ping from router 1 (192.168.1.2) to router 2 (192.168.3.2)?

Strange.

 

[Jsteve]

now you can set the ip on the switch.

than on each router, you must advertise the networks that are direcctly connect. you must do these two steps on each router,

1) sh ip interfave brief. From this command you will see each network that you must advertise.

2)advertise the network under rip
i.e.
#config t
#router rip
#network 192.168.1.0
#network 192.168.2.0
an so on.

 

[Jsteve]

Once you advertise your networks, each router will now about the other networks.

 

[Jsteve]

Gotta run dude, keep the faith
