Internet Connection to Vlan that is not Vlan1 - N3000 SERIES
Hello. I got a problem that is making me want to kill myself.
I have this "topology":
/ SwitchLab(N3024) / - - - - - - - - - > / Lab PCs (VLAN 100, 192.168.100.1) /
||
(trunk between Switches)
||
/ SwitchCORE(N3024) / - - - - - - > / DHCP Server (192.168.1.1) / - - - - - > / Router or Internet Provider /
||
/ Other PCs (VLAN 1 native and default, 192.168.1.0) /
The point is that I've already configured "ip routing" for both VLAN 100 and the VLAN 1 (native vlan) to route between these vlans. And I also configured the SwitchCORE to forward traffic from the VLAN100 to the final DHCP Server (192.168.1.1).
(I'm convinced that the DHCPServer should deliver the packages from VLAN 100 to the Router/Internet provider.
It is necessary (and indispensable) to configure the Router/Internet to receive and forward the packages from VLAN 100 to external Internet???).
(Am I wrong when I'm thinking that the Internet access should be already working even without configuring the Router/Internet Provider?)

Hi,
Can the device on the .100 network ping devices on the .1 network? Are they getting DHCP addresses?

Answering your questions:
1. Devices on the .7 network can ping only the VLAN 1 on both Switches (192.168.1.244 and 192.168.1.230)... they can not not ping .1 devices/PCs.
2. Static ip adresses had been assigned for the devices on VLAN 7 (.7 network).
(Ignore .100 network and consider it's .7, instead.)

To help you guys to understand the case... it might help (there's this picture too): https://www.dropbox.com/s/iid6div8eygvo8e/actual-config.PNG?dl=0
- - - - The "before" scenario:
All the devices (including the N3024 switches) are on the default configurations (we bought the switches and plug them all). So all the devices/switches are in the default VLAN (VLAN 1) and getting normally conections to the Internet (the Defaul Gateway of the VLAN 1 is the DHCP Server 192.168.1.1).
------ And now...
I need to set all PCs that are in a room of the building to VLAN 7. In this room, there's a N3024 switch. In this switch I created the VLAN 7 and setted some ports to access the VLAN 7. Also enable 'ip routing' in both Switches. (See the picture).
(In my mind, with just the 'ip routing' enabled and the routes, the packets from the PCs of the VLAN 7 would do this path):
/ PC (192.168.7.1) / >>>> Room Switch (192.168.7.100) >>>> CORE Switch (192.168.1.244 or 192.168.7.200) >>>> DHCP Server (192.168.1.1) >>>> Switch and Router from ISP >>>> Internet
I also tried the configuration settings that is in the page 1171 of the "Dell EMC Networking N-Series Switches User Guide version 6.6.1", but it was no sucesfull: https://www.dropbox.com/s/h64qsq1pdn86ovs/man%20example.PNG?dl=0

Do they show the routes when you look? does the room switch have a trunk port to the core?

Yes. They show the routes.
Yes. Both have a trunk port.
As long as I'm working from home, I'm don't have access to the switches yet.
On both switches, when I run the 'show ip route' command, it shows the routes.
(In my packet tracer simulation it's not showing... I'm working from home, and I don't have access to the switches right now).
If it helps... I don't have to communicate the PCs on the VLAN 1 with the VLAN 7 PCs, excepts, of course, the DHCP Server (192.168.1.1), wich is the gateway of the entire network/LAN. I know that it's a Debian Server... and I'm thinking that, in this case, the "route" must be configured in that Debian Server.
