  • 1.  Problem performing routing between VLAN

    Hi, i need to perform interVLAN routing in order to allow devices in different VLAN to see each other.
    Right now i've setup a RIP Router and use IP RIP V1-only in the VLAN than has to communicate but unfortunately the VLAN still won't communicate at all.

    UPDATE: Configuration file is attached.


    Devices on VLAN 1,3 and 11 needs to see each other and communicate, but right now i cannot ping/traceroute any of them from one VLAN to the other. 


    #interVLANRouting

    Devices on VLANs should just set their default gateway to L3 switchIP address in their subnet.
    The switch has routes to all direct attached networks, so you won't need a routing protocol.

    Never ever use RIP-v1.  It's classful only, so you can't advertise subnet masks.
    172.16.x.x is ClassB address , having /16 mask so all your subnets fall are in the same in the same RIP advertisement.

    Changing subnet doesn't solve the problem unfortunately

    In any case i can ping the gateway for each VLAN and still i cannot direct my traffic from one VLAN to another.

    There's no need to change the subnets. Just make sure that:
    All clients in 172.16.1..0/24 network have set their gateway to 172.16.1.1
    All clients in 172.16.3..0/24 network have set their  gateway to 172.16.3.1
    All clients in 172.16.1.1.0/24 network have set their  gateway to 172.16.11.1

    The client gateway configuration is correct and I can ping the gateway without problem. I still cannot ping and access devices from one vlan to another.

    On the switch, what is the output of following commands?
    show arp
    show ip route
    show ip

    output shows:
    IP routing is enabled, route table contains all connected networks.
    As only 3 stations made it to the ARP table , I doubt stations use correct IP subnet or wrong gateway.

    Try pinging/traceroute among those 3 stations, and make sure their firewall is turned off.

    Did you look at this topic:  Similar switch that needed firmware update to enable IP routing
