Need Help in Setting up InterVLAN Routing on PC6624

Jump to solution

Hi,

I have stack of 5 Dell PC 5548 Switches and 1 switch of PC 6624 for Layer 3 routing.

I have connected Stack to PC6624 using 10 GB Fiber cable.

I have created multiple VLANs on Layer 2 Stack. Now How can I configure Inter VLAN communication using PC 6624 switch?

Regards

Hi,

Page 507 of the manual explains how to enabled IP routing on the switch ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_powerconnect/powerconnect-6248_Us...

 

Here is a document explaining the configuration on an older switch, the concepts are the same http://www.dell.com/downloads/global/products/pwcnt/en/app_note_38.pdf

Scenario:
VLAN 10 -> 1/0/2 to 1/0/48
                      2/0/1 to 2/0/14

VLAN20  ->  2/0/15 to 2/0/48               
                      3/0/1 to 3/0/26


                        VLAN IP address on L3            VLAN IP address on L2

VLAN 10 -->       172.16.10.250/24                     172.16.10.249/24
VLAN 20 -->       172.16.8.254 /24                      172.16.8.253/24

==============================


Laptop 50  --> 172.16.10.50/24    --> VLAN10
Laptop 81  --> 172.16.8.81/24    --> VLAN20


Till today,
- I Stacked L2 Switches

- Connected L3 and L2 switches with OM3 FC.

- Created 2 VLANs on L3 Switch VLAN 10 & 20

- Assigned IP addresses to both VLANs on L3.
    "VLAN 10" -> 172.16.10.250/24
    "VLAN 20" -> 172.16.8.254/24

- Configured Fiber Port on L3 which is connected to L2 Stack as Trunk Port

- Allowed both VLANs from Trunk using Switchport command.

- Created  Both VLANs on L2 Switch.

- Assigned IP addresses to both VLANs on L2
    "VLAN 10" -> 172.16.10.249/24
    "VLAN 20" -> 172.16.8.253/24

- Created IP route on L3 switch
ip route 172.16.10.0 255.255.255.0 172.16.10.249
ip route 172.16.8.0 255.255.255.0 172.16.8.253

- Assigned Appropriate Ports to VLAN

- Provided Default Gateway to "Laptop 50" --> Gw 172.16.10.249
                                            "Laptop 81" --> Gw 172.16.8.253

- Now I could able to ping "Laptop 81" from "Laptop 50"

Queries:
1. Is this a correct method for Setting up VLANs and InterVLAN routing ?
2. Here in Laptops I had to provide default gateways as IP of VLAN interface on L2. But then How can they connect to Internet?
3. Here I had used 255.255.255.0 subnet mask. But in actual we are using 255.255.0.0 subnet mask. then will it work?
   Because as far as I know Routing only works between 2 different subnets. So How can I achieve InterVLAN communication without IP routing? So that I dont have to change IP addresses of Desktops.

Hi,

That configuration looks correct. IP routing can be done between VLANs on the same subnet, if you enable it globally it should work on all of the VLANs the switch is aware of. If the switchports are set to general they can route all of the VLANs assigned to them. For getting the clients on the internet, is the router handling DHCP or another device, as long as they can access the router through the various VLANs they should be able to get to the internet.
