I am new to cisco, and I got a project for school. I have to make a small office.
I got a couple of problems that I would like to solve.
1. I gave my switches and routers a IP on
VLAN 1
but I can only ping one switch
(L3-SW-01)
All the rest i can't ping.
2. I have also to do SSH on my switches and routers. But only my IT department has to do it. And this is in VLAN 60.
All the passwords on the switches and routers are: robbie
Here is the network file.
Thanks in advance.
Solved! Go to Solution.

Thx for helping my out. I really appreciate it.
But now I have to try pinging to my
CORE-R1 and R2
They both have already an IP in
VLAN 1
They are connected to the layer 3 switch. I need to use Static routing. What I also did.

The way you did will not work.
If you want to keep the
vlan 1
on the router on the same network
192.168.125.0 /28
you need to have Layer2 between the L3 switch and router.
The L3 switch will not send packets to a remote network IF it has this network on it. Do you get this?
You have this on the L3 switch.
Vlan1 192.168.125.115
YES manual up up
So that, if you try to ping anything on the
Vlan 1 (192.168.125.0)
the L3 switch will look into Vlan1, it will not send it out a Layer 3 interface to get to the router.
Either you use layer2 connection between L3 switch and Router or you use a different IP to manage the Routers.
