Hi All,
I am looking for the best practices on routing a bunch of subnets and their respective VLANs between two seperate sites over a single private 10Gb link.
I have a stack of 6248 switches and an 8024F switch. One has threesubnets and three VLANs, the other has two subnets and two VLANs. I basically just want traffic from every VLAN to be routable across the 10Gb link from each side.
Trunking was suggested, but I tested that in my lab and it does not seem to work. Perhaps I am missing something, but this issue is really frustrating us since no one seems to be able to assist in what needs to be done.
Please let me know if more information is needed.
Thanks!
Trunk Links attach two VLAN aware switches (or other VLAN aware devices) together and allows for multiple VLAN frames to cross one link.
On VLAN trunk links, all frames must be tagged with the respective VLAN ID’s
The native VLAN must match on all switches in the segment. (VLAN 1 is default Native VLAN). The native VLAN is NOT tagged.
Here is a sample of command line. You would want to run this on the interface or lag on both switches where they are connected.
Configuring Trunk Ports
console> enable
console# config
console(config)# interface ethernet 1/e5
console(config-if)# switchport mode trunk
console(config-if)# switchport trunk allowed vlan add 2
console(config-if)# end
console# show vlan

Dell -Willy M, thanks for the response. It was trunking that solved the issue, but I also had another post open with Dell -Daniel Co, so we determined that a direct routed VLAN between the 10Gb connections also needed to be created since both switches had to remain L3 devices.
I created a new VLAn with a /30 subnet and added this to both switches on either end of the 10Gb, then made the 10Gb ports trunk members in this new VLAN.
Lastly, I created a bunch of static routes for the VLANs/Subnets to direct traffic across the 10Gb in either direction.
This works, great, so thanks for the input.
