MS250 - Static routes amd L3 routing

Facing issues with VLANs, as we need MS250 switches to handle the DHCP and L3 routing by itself

After configuring the VLANs we cant add static routes, only one there by default.

Because of this only one VLAN has the static route can run dhcp with internet access.

 

other VLANs can run dhcp but without internet

So we need to add multiple static routes.

 

Can anyone provide solution for this issue.

Exactly Philip, whatever is the next device downstream will need a static route back to any subnets that are not on the same VLAN as the connected VLAN.  If you don't give it this, then it's only going to see the VLAN that it is connected to on the Meraki.

 

This is assuming the devices are not using any dynamic routing protocols, of course.

Re: MS250 - Static routes amd L3 routing

do you mean no more default routes?

what error you get when you add  a static route?

 

the static routes are not for specific vlans but for the routing process of the switch. so all vlans can use them.

Re: MS250 - Static routes amd L3 routing

At a time only one VLAN can use the static route corresponds to the same subnet.

 

other VLANs worked with own dhcp range but with dns issue.

 

that is the reason we look to add static route for each VLAN.

 

Here all VLAN has own dhcp..at current only one VLAN which has one static that becomes default is working fine with dns.

 

when we tried to add more static route for each VLAN inorder to get proper gateway..system shows error the subnet already routed.

Re: MS250 - Static routes amd L3 routing

all vlans are already routed if you created them on the MS L3 switch.

You just need to add the default route 0.0.0.0/0 to the next hop IP(your internet gateway/router)

Re: MS250 - Static routes amd L3 routing

Also note that whatever is your "default route" will also need return routes to the subnets being routed by the MS250 via the MS250.

 

Check out this example:
