Routing from VLAN 1 to VLAN X in all Hybrid mode.
So we have really simple network with 4 VLANs in total on stacked Force10 MXL switch and Juniper SRX. Networks are like below;
1 (untagged) -> 10.100.0.0/16 -> Gateway is Juniper (with IP 10.100.0.1) -> No IP on switch 20 (tagged) -> 10.2.0.0/16 -> Gateway is Juniper (with IP 10.2.0.1) -> Switch IP: 10.2.0.2 40 (tagged) -> 10.4.0.0/16 -> Gateway is Juniper (with IP 10.4.0.1) -> No IP on switch 80 (tagged) -> 10.8.0.0/16 -> Gateway is Juniper (with IP 10.8.0.1) -> No IP on switch
1 -> management & servers
20 -> Storage
40 -> Clients Group A
80 -> Clients Group B
All ports are;
- in hybrid mode.
- no shutdown
- has all 4 VLANs configured
In this scenario when a server needs to reach to a storage in the network we create a VLAN on that server and tag it. Then set a new IP for that interface and create the connection. And this is working without any problem.
However right now we need to make servers running on VLAN 1 needs to talk to storage on VLAN 20 without any tagging.
How can I do this ?

Typically you would see the core switch perform L3 routing between the VLANs. This would allow VLAN 1 to communicate with VLAN 20. Is the Juniper your core switch? Which switch is the storage connected to? You should be able to have one of the switches route between the VLANs.
Here is a Juniper KB article on VLAN routing: https://juni.pr/2uLoZzP
The process on the MXL is pretty straightforward: https://bit.ly/1Kgcs8e

Yes Juniper is the core switch.
However we dont want to create unnecessary load on Juniper, increase complexity and increase the number of hops.
The real problem is that we need to make the change without distrupting current network.

Some configuration changes will need to be made. Whether this is continuing to add the VLANs to the server, or having the MXL or Juniper route between the VLANs.

Now I think I found out something; switch has a management IP like 10.100.0.5.
If I set the gateway for server as 10.100.0.5 may I reach storage network ? OR if I set a new IP to VLAN 1 for switch, lets say 10.100.0.10, and set the gateway of specific server as 10.100.0.10, may I reach that network ?
What do you think ?

Before looking at what IP should be used for the default gateway, I suggest identifying which device is going to route between VLANs.
Seeing as the Juniper has IP addresses on all the VLANs, and looks to be the gateway for those VLANs, I will use it in this example.
Juniper is configured to route between VLANs.
Juniper has an IP for VLAN 1 and VLAN 20.
server has an IP in the 10.100.0.0 subnet.
server has a default gateway set to the Juniper VLAN 1 IP address, 10.100.0.1
If you want to share the configurations, I would be happy to help look through them.
