Noob Routing Question

[wjonline1975]

Hi,

into my first hour with meraki switches : MS250-24P.

I have my management interface on vlan1 and it has been assigned an IP via DHCP, and thus it can route out and connect to the cloud.

so I see the switch online and all looks good.

I want to add vlan 50, so I assigned a port as access and placed it into vlan 50.

I want to make vlan 50 a L3 vlan, so I click on "configure layer3 settings".

I get presented with a screen that states:

"You don't have any interfaces or static routes configured

Create an interface to configure layer 3 settings on your switch", so I click.

I select the switch from the dropdown and the following details:

name = "v50"

subnet = "10.10.93.0/24"

interface IP = "10.10.93.254"

default gateway = ""

vlan = "50"

then hit save

I get the following error message?

"There were errors in saving this configuration:

• The interface on 10.10.93.0/24 overlaps the interface on 0.0.0.0/0"

any ideas, im stumped?

I guess You did not inserts the default gateway so it cant create the default route to that gateway ip.

Hi

So from what you have said that the vlan1 interface that has received an IP via DHCP and does have a gateway is not installing a default route into the routing table?

thanks
