1st time poster, I am trying to get two vlans talking to each other with out using a router. As I understand it the 3750 is layer 3 capable there for I would like to be able to get vlan 10 out to my router to the internet. What is going is I have 4 Hosts for Virtualization and it needs to get out the internet to get images down to the nodes. I am using Joyent Triton Datacenter so you know (This has to be on it's own segment because it uses pxe boot w/dhcp to configure Compute Nodes). I already have a dhcp server on Vlan1.

Is vlan tagging an option? If so can someone point to a good tutorial to help me learn it.

Vlan1 consist of fastEthernet0/1 Through fastEthernet0/9 Vlan10 consist of fastEthernet0/10 Through fastEthernet0/19(This needs to be able to talk to the internet).

Vlan1 ip is xxx.xxx.1.0 Vlan10 ip is xxx.xxx.10.0

Here is the Vlan setup

show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

C    xxx.xxx.10.0/24 is directly connected, Vlan10
C*   xxx.xxx.1.0/24 is directly connected, Vlan1

Vlan1 is the default network

The router I have is a Netgear Router not able to trunk, I know I know but it's the best I can do at the moment. and I need the Wifi.

If someone could help get this done I have configured it all the way to this point but now I am stuck here, I have been studyng interVLAN routing, I am just not sure how to finish this.

note: I know a bit about networking but I am not a Network Admin or Engineer

Thanks in Advance,

I have my configs and network picsMy Network

Michael P S I have my configs in a text file also if anyone wants to see them to help me resolve this. FYI Switch 2 is the one in question.

Thanks Again,

Assuming you have the correct licensing, you would need to globally enable IP routing on the switch:

 ip routing

You can then create layer-3 interfaces. Add IP addresses to SVIs, and/or use the no switchport command on a physical interface to allow you to configure the interface as a router interface.

You can configure the interface to you router as a routed link.

The problem you are going to have is that the router will need to be told how to reach the networks on the other side of your layer-3 switch. If the router doesn't specifically know to send traffic for those networks to the layer-3 switch, it will send the traffic to its default route, probably the Internet.

Routers learn routes in three ways:

  1. Directly connected networks
  2. Statically configured routes
  3. Through a dynamic routing protocol

Obviously, the first method is out for your router, so you will need to use one of the other two methods. Unfortunately, your consumer-grade router is off-topic here, so we cannot help you with its configuration.
