I need some help making sure my three Cisco SG300-10 L3 switches are configured correctly for inter vlan and interswitch L3 routing on my network. I have a relatively simple setup with two goals – improve network speed (use L3) and
**I need to isolate Guest VLAN so they have access to the internet but not the network devices and Main devices**
Router 192.168.1.1 (DHCP server is here)
Switch 2 – 192.168.1.2
Switch 3 – 192.168.1.3
Switch 4 – 192.168.1.4
My setup is as follows:
Router( non-Cisco): 192.168.1.1 -> connected to switch 2 (192.168.1.2) -> connected to switch 3 -> connected to Switch 4 (192.168.1.4)
Set switches up as L3, and set account settings, time etc (Basic Stuff)
Assign an IP address 192.168.1.x (x=2, 3 or 4) for each of the three switches
Create VLAN 2 and 22 on each switch
I have enabled VLANS as follows on the router and switches
VLAN 1: 192.168.1.0 Network Devices
VLAN 2: 192.168.2.0 Main Network
VLAN 22: 192.168.22.0 Guest Network
4. Do Port Mapping for the ports for VLAN 1,2, or 22 for trunk access and VLAN access
5. IPV4 Routes **DO. I NEED TO ADD ANY ROUTES TO EACH OF THE OTHER SWITCHES and the MAIN ROUTER????***
If so then I need to add route as follows?
For Switch 192.168.1.2 set up VLAN2 to other switches
Destination IP 192.168.2.3 for switch 192.168.1.2
Next Hop 192.168.1.3
Metric: 1 (default)
Destination IP 192.168.2.4 for switch 192.168.1.2
Same Prefix, Remote and Metric
Next Hop 192.168.1.4
ROUTE BACK TO ROUTER OR IS THAT ALREADY THERE???
Destination IP 192.168.2.1
Remote, Metric, Prefix
Next Hop: 192.168.1.1
DO the same for the other two switches for VLAN 2
Repeat the above routes for VLAN 22 the same way or different cuz it is isolated
6. Set DNS to 192.168.1.1 for 1, 126.96.36.199 for 2….. for each of the switches
7. ANYTHING ELSE TO ISOLATE VLAN22 from network other than internet?
8. DO I NEED TO SET ANY ADDITIONAL ROUTES FROM MY ROUTER TO THE SWITCHES???
