6024 Basic VLAN Routing

Question

Hello,      I have read all the posts about Routing VLAN's and I am still not getting it to work.  Please help!      Here is my setup.  I have a Dell 6024.  I have setup one new vlan so that I have the original VLAN 1 and the new VLAN 10.  The systems on VLAN 1 have ip addresses 172.16.10.x, the system on VLAN 10 has the ip address 10.10.10.x.  I am unable to see systems on VLAN 1 from VLAN 10, and vice versa.  Here is my current configuration:     console# show running-config Router Configuration ----------------------------- vlan database vlan 10 exit interface ethernet g19 switchport access vlan 10 exit interface vlan 1 ip address 172.16.10.254 255.255.255.0 exit interface vlan 10 ip address 10.10.10.1 255.255.255.0 exit router rip enable username admin password 5f4dcc3b5aa765d61d8327deb882cf99 level 15 encrypted snmp-server community Dell_Network_Manager rw view DefaultSuper console#   Can someone please tell me what I am missing?  It was my understanding that if I just created the VLAN and then assigned each an IP address that I would be able to pass data between the two?  Is that wrong?  Do I need to do something else?   Thanks, Eric

Some added notes.  I found that I had the wrong gateway on the unit on the 10.10.10.x side.  So that unit now has the gateway of 10.10.10.1.   I also found that by giving a unit on the other side (172.16.10.x) the gateway of 172.16.10.254 that they are then able to talk to each other.   However, I am still unable to reach the other units that have a 172.16.10.x address as their Gateway is 172.16.10.1.  Am I going to have to change all those to 172.16.10.254?  Then how do I get internet access?   I tried to use IP Route to get internet access for the 10.10.10.x machine, but it did not work. Here was the command I used: ip route 0.0.0.0 0.0.0.0 172.16.10.1 Then I tried ip route 10.10.10.0 0.0.0.0 172.16.10.1 But got nothing.   To be more specific about what I am trying to do...right now we have a flat network, everyone is on 172.16.10.x.  We have an Engineering department that is sending out a lot of UDP traffic.  I was hoping to put them on their own VLAN there by blocking that UDP traffic.  However, the will still need to be able to see machines on the 172.16.10.x network and access the intenet.

I am assuming this is the entirity of the network. you have: vlan 1: 172.16.10.254 /X vlan 10: 10.10.10.1 /X   You will need to make the default gateway for the clients connected the ip address of the respective vlan   the if the route out from the 6024 is 172.16.10.1 the route needs to be: ip route 0.0.0.0 0.0.0.0 172.16.10.1     on the router or firewall make sure you have your static routes coming back in   ip route 10.10.10.0 255.255.255.0 172.16.10.254   Hope this helps,

Do you know how I change the Default Gateway?

I tried

console(config)#ip default-gateway 172.16.10.1

and it says it is an unrecognized command...any ideas?

One more time, here is what I am trying to do..

I have one machine that is 172.16.20.20 and one machine that is 172.16.10.16. My firewall/router is 172.16.10.1

I need the two machines to talk to each other and then both machines be able to access the internet through my firewall/router.

Thanks.

The 6024 is a Layer 3 switch, so you can route between different IP subnets.  You just need to TURN ON 'routing' for each VLAN on the 6024.   This may help too:  http://www.dell.com/downloads/global/products/pwcnt/en/app_note_38.pdf     Point the 6024's default gateway towards your Internet Router for a path to the Internet.

Sorry, I used the wrong terminology for this switch.  Drgnslyr's post was correct.  Set the route to: ip route 0.0.0.0 0.0.0.0 172.16.10.1   It looks like the only thing that you're missing is that you need to enable 'routing' on your VLANs.
