2930f intervlan routing

  • 1.  2930f intervlan routing

    Posted Aug 12, 2017 05:07 AM



    i have 3 vlans, vlan10, vlan20 and vlan30 in my single ARUBA 2930F switch ang connected to my FW... i need to know if i can make intervlan routing by using this single switch alone? like i plug my laptop in vlan10 and pc in vlan20, will they have routing between each other? is it possible without touching the FW/..thanks

    It depends where is your gateway defined.

    If your switch is acting as gateway for both subnets, it can route traffic between the,

    If switch is configured as a Layer 2 device and firewall is your gateway for clients, routing has to be done on firewall.


    2930 is a basic layer 3 switch and is capable to do inter VLAN routing.

    I just responded to this thread:




    It looks the same.  Let me know when this is different.

    You cannot have both commands "ip routing" and "ip default-gateway x.x.x.x" at the same time configured at the switch.


    If you want to make intervlan routing, all three interfaces vlan (10, 20 and 30) must be created at the switch as the default gateway of each network.


    Also, maintain only the "ip routing" command with a default static route to your firewall "ip route"

    IP default-gateway is only for the switch itself, so let's say management traffic. For all other traffic, you have IP routing. When no dynamic routing protocol configured this will be directly connected routes in combination with static routes. Hope this makes it clear.

    You mention that you're trying to ping between systems on VLANs 10 and 12; I'll note that VLAN 12 is assigned an IP address on a /30 subnet, so there could only be one other device on that subnet (which appears to be the switch default route).


    Are your devices pointing to the switch IP address on their respective VLANs as the default gateway? (A device on VLAN 10 should point to, and one on VLAN 12 should point to
