Hello experts,
I am struggling to wrap my head around how I need to configure my external switch or if I even need it anymore.
The switch needs to be replaced and I was hoping to just cut it out altogether. It basically performs one more step of routing from my range of IPs allocated to me by my ISP to the ISPs static IP address.
Core - InsSwi - Meraki - ExtSwi - ISP
that's how I am currently set up.
all my clients are on a 10.0.0.0/8 network
i have a subnet of 192.168.50.0/24 that connects my core to the other gear (inside switch, meraki, web reporters, etc)
I have a L2 switch that I was messing around with to replace my external switch and so i was trying to set up some static routes. here is my current configuration on the new switch that is not working
ip routing
interface GigabitEthernet1/0/23
switchport access vlan 300
switchport mode access
!
interface GigabitEthernet1/0/24
switchport access vlan 301
switchport mode access
!
interface Vlan1
no ip address
shutdown
!
interface vlan300
ip address 216.222.222.254 255.255.255.0
no ip route-cache
!
interface vlan301
ip address 195.1.1.2 255.255.255.252
no ip route-cache
!
ip route 0.0.0.0 0.0.0.0 195.1.1.1
ip route 216.222.222.0 255.255.255.0 216.222.222.250
--------------------------------
this is my current configuration that is working

any suggestions would be greatly appreciated

One golden rule I know is: less hop you have between you and the destination is better. This means less power consumption, less processing, less delay, less point of failure, etc,etc.
No one here can knows your environment better then you, but, as per your description and config, I'd say you should cut it off.
The only question I know is, are you able to connect the ISP in other device? According to the diagram this device looks to be Meraki. But, is it Meraki, able to receive your ISP connection?
