When you enable routing on VLT peers, you can also enable the peer routing feature. In a nutshell, when peer-routing is enabled on both VLT switches you can load-balance, the L3 packets through both switches — as this allows a switch in VLT domain to forward traffic on behalf of its peer switch. Images taken from Configuration guide. Peer-routing helps to avoid sub-optimal routing, reduces the latency by avoiding another hop in traffic path, no need to have VRRP.

So basically by enabling peer routing we have only one goal — redundancy and traffic sharing for L3 protocols. Routed VLT v1. You are commenting using your WordPress.

I have attached my current setup below. Using this setup i have 2 servers configured with an LACP team.

It works great, i disable an NIC the other one is working within seconds. However, i want to segregate this traffic onto a VLAN.

I can also get this to work, however i cant get it to work in conjunction with LACP and when creating a team the ports dont failover properly. To enable the VLAN configuration i used the same as below, however i also added this to both of the port channels on both switches. Is there something that i am missing?

Sorry if this is such a basic question, i have been reading the dell manual but its 's of pages and i learn better by seeing how things dont work then do work!

Which OS version is it? What happens if you shut down the port channel and re-enable it? Sorry did you mean still use VLAN but dont specify it under vlan trunk allow? I have then tried to tag the ports as access and VLAN on the switches and that works fine, but ideally i want to be able to pass multiple VLANs through the same ports on the switch. Browse Community.

A number of enhancement have happened to the protocol since my initial posts many years ago. The content that was true for a feature, on a particular code revision 4 years ago — may not, and infact will not in its entirety be true for the current software revision.

Layer 2 Loop detection mechanism: VLT does eliminate bandwidth wastage via Active-Active links, nevertheless you will still have a spanning tree protocol in the background as a failsafe. VLT interconnect over 1G is not supported. During normal operation, it is not intended to pass user traffic.

Dell EMC Networking SmartFabric Director Accelerate IT transformation by enabling a more agile and simplified central management across both virtual and physical network infrastructures. Explore All Network Operating Systems.Virtual Link Trunking or VLT is a proprietary aggregation protocol developed by Force10 and available in their datacenter-class or enterprise-class network switches. VLT is a layer-2 link aggregation protocol between end-devices servers connected to different access-switches, offering these servers a redundant, load-balancing connection to the core-network in a loop-free environment, eliminating the requirement for the use of a spanning-tree protocol.

Beside increasing bandwidth another reason for link aggregation is redundancy. To make it possible to connect a LAG to different physical switches is to combine more than one physical switch into one logical switch using switch stacking techniques where the different physical boxes are seen as one logical switch for management and spanning-tree topology.

The switches running in a stacked configuration always have to run the same firmware, which means that in case of a firmware upgrade the network manager has to implement the new firmware on all stack-members at the same time, resulting in an outage of the entire stack.

The alternative is to have different logical switches, but then one of the used links will have to be blocked to ensure a loop-free topology which can partially be overcome by using Multiple Spanning Tree or Cisco 's proprietary per VLAN spanning tree.

Spanning Tree Protocol is relatively slow in convergence, which can result in periods that traffic can't be forwarded over the network - and thus leads to outages of the applications. VLT should address all these issues, making it possible to create a loop free redundant network topology without using the Spanning Tree Protocol.

Repeat the same configuration on both switches. Do the same on the second switch, but now point to the first switch management IP for backup and use the highest priority to make this switch a secondary peer:. As you can see, the VLTi and backup links are up and the switch can see its peer. For some additional VLT specific information use these commands:. I would also recommend to use the following command to see the port channel state and confirm that both VLTi links are in up state:.

In this part of the Dell Force10 switch configuration series we quickly went through the initial VLT setup. This entry was posted on July 31, at am and is filed under Networking. You can follow any responses to this entry through the RSS 2. You can leave a responseor trackback from your own site.

This is a very good point. There are a number of recommended parameters that can make your configuration more deterministic and improve convergence, this includes RSTP tuning, port dampening and VLT system parameters. In this series I tried to explain the basics.
