Switch Force10 S4810 - TRILL or VLT
Hello
I have 3 Force10 S4810 and I want to interconect them in a ring topology:
Switch1----------------Switch2
| |
|______Switch3______|
But I don´t want any link blocked by Spanning-Tree. I read that Force10 has support for TRILL or VLT. Which is the best to achieve this purpose? All links enabled and being used.
What configurations should I place to make this work?
I really apreciate your help.
Best regards
BGCC

I apologize I am not real familiar with the Force10 products, I would suggest contact the Force10 support group directly for an accurate and prompt answer.

VLT should serve the purpose.
it is very similar to Cisco vPC in operation. I have implemented it on a couple of Force10 rollouts, did not face any issues.
With VLT, when you have a downstream switches connecting to two upstream switches which are a separate logical backplanes (not stacked), the downstream switch will view them as a single logical chassis. thus, LAG or aggregate ports can be split between the two upstream switches without a problem.
for any switches upstream to the force10 VLT peers, they will continue to view these as separate switches.
As far as your requirement goes, VLT would give you this active active redundancy as long as you are using LAGs across the two upstream switches from the downstream switch.
do you have the details on how you would configure and setup VLT?

Yes Richter. VLT is designed to serve that purpose only..
Configuration is as follows:
Switch1:
1) Form a static portchannel between switch one and two and an LACP portchannel between Sw1 And 3.
