add layer 3 switches to existing network

Hi

 

We need to add layer 3 switch (MS-250 Meraki)  to perform intervlan

we have SAS 5506 That connect to vpn (Anyconnect) in vlan 1 ip 192.168.1.1

all connection go from this vlan 1 to the server,workstation,printer,vpn......

we need to divide our network to  intervlan 20,30 and keep vlan 1 manage our server and printer

Vlan 1 for server and printer 192.168.1.0/24(because we can not change server and printer  ips)

intervlan for workstation 192.168.20.0/24

intervlan for wifi 192.168.30.0/24

we alredy create the intervlan interface in the switch and the scope in dhcp server 

Name   

Subnet 

IP interface

VLAN id 

DHCP Settings

Mangement vlan 

192.168.1.0/24

192.168.1.3

1

off

workstation vlan

192.168.20.0/24

192.168.20.3 20

20

Relay to dhcp server

wifi vlan

192.168.30.0/24

192.168.30.3 30

30

Relay to dhcp server

 

 

Dhcp server 2016 : 192.168.1.10

we create scope using the switch's routing interface for each VLAN as the gateway

192.168.1.1 for scope 1

192.168.20.3 for scope 20

192.168.30.3.for scope 30

Problem:

we start move same workstation to vlan 20 for test

Device in vlan 20 Take adress in vlan 20 , DHCP work fine , but  no internet to this device 

I can not ping any address from vlan 1 when i'm using  vlan 20 or 30 to , but ping work fine between vlan 20 and 30

 

Questions:

 

how to have traffic between my Layer 3 intervlans .Vlan 20 , vlan 30 and vlan 1(native vlan)
until now my pings are succesfull between vlan 20 and 30 but unseccesful when trying to ping vlan 1(native vlan that have all my servers) from vlan 20 and 30

 

 

Thank you

 

Please Advice

You cant ping devices in vlan 1 because they have as gateway your 5506. But the 5506 does not know where vlan 20 and 30 are.  So you need to create the static routes.

Ip route 192.168.20.0 255.255.255.0 192.168.1.3

Ip route 192.168.30.0 etc..
