Evlt Configuration Example - Dell Z9500 Configuration Manual

Configure PVST+ on VLT Peers to Prevent Forwarding Loops (VLT Peer 1)
Dell_VLTpeer1(conf)#protocol spanning-tree pvst
Dell_VLTpeer1(conf-pvst)#no disable
Dell_VLTpeer1(conf-pvst)#vlan 1000 bridge-priority 0
Configure PVST+ on VLT Peers to Prevent Forwarding Loops (VLT Peer 2)
Dell_VLTpeer2(conf)#protocol spanning-tree pvst
Dell_VLTpeer2(conf-pvst)#no disable
Dell_VLTpeer2(conf-pvst)#vlan 1000 bridge-priority 4096
Configure both ends of the VLT interconnect trunk with identical PVST+ configurations. When you enable VLT, the show
spanning-tree pvst brief command output displays VLT information.

eVLT Configuration Example

The following example demonstrates the steps to configure enhanced VLT (eVLT) in a network.
In this example, you are configuring two domains. Domain 1 consists of Peer 1 and Peer 2; Domain 2 consists of Peer 3 and
Peer 4, as shown in the following example.
In Domain 1, configure Peer 1 fist, then configure Peer 2. When that is complete, perform the same steps for the peer nodes in
Domain 2. The interface used in this example is TenGigabitEthernet.
