Unicast w/Catalyst 2960xr

SDCAdmin
Level 1
Level 1

Hello! I just started working as Office/IT admin of a start up Datacenter. We've purchased two blocks of IPv4 addresses from local fiber ISP. We want to make sure the servers secure. ISP advised us to set up IP Unicast. We are using a subnet mask of /24 to break down the blocks in to 32 Subnets with 8 hosts (5 total useable IPv4 addresses). Problem is my Networking chops are 10+ years old. So relearning this as I go.Here is the diagram I was given from the ISP. IP Unicast.jpeg

subnet address 148.59.35.24

gateway address 148.59.35.25

host address range is 148.59.35.26-148.59.35.30

broadcast address 148.59.35.31

 

Switch: Cisco Catalyst 2960xr

Fiber ISP

 

 

I'm using this source:(https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960xr/software/15-0_2_EX1/routing/configuration_guide/b_rt_152ex1_2960-xr_cg/b_rt_152ex1_2960-xr_cg_chapter_011.html#d3590e8278a1635) 

I've tried to follow guide but I am unable to ping the router address. I am sure I don't have the correct protocols and IP addresses assigned correctly. VLAN1 is running servers that are hosting websites and the Office network.  Would like to reload switch, but I am unsure how long that process is and what effect it would have on the servers currently in use.

 

some error messages I am getting are:

I need to know:

What protocols to enable/disable 

How do I resolve the IP address Overlap

 

I found it hard to decipher from the guilde which steps I needed to do and the steps I didn't. Could you provide a simplified list of steps so I am sure I am not missing steps as I go.

 

I know its a lot to ask, but help a Girl out! (I applied for IT assistant and ended up being the IT admin. I'm very happy to get back into IT after 10+ years, but this has been a stressful last few days!)

 

Thanks in advance!

interface GigabitEthernet1/0/4

 no switchport

 ip address 148.59.35.2 255.255.255.0   <--- because of this you are not able to configure other IP

                                                                 <--- as per your description you did subnetted with /24 subnet.

 

So change this to
