Next, the VLANs will be configured. There will be one VLAN for each Isilon subnet; this will also include the
servers in each rack. Virtual Router Redundancy Protocol (VRRP) will be used to as a secondary from of
redundancy. Although VRRP is an active/standby First Hop Redundancy Protocol (FHRP), when combined
with VLT it becomes active/active. The priority is assigned to give predictability of VRRP master. The higher
priority will be elected as the master. If no priority is given, the higher IP address will be elected as the
master.

Note: Further information on all protocols used in this document and their use cases can be found in the
Dell EMC Leaf-Spine Deployment Guide and Dell EMC Networking L3 Design for Leaf-Spine with OS10EE.
Configure the necessary port channels. There will be one port channel for each server as well as a single port
channel for each of the Isilon nodes. Each port channel is assigned an MTU of 9216 to support jumbo
frames, as well configured to allow access to VLAN 100. The vlt-port-channel command enables port
channels on VLT peers to function as a single port channel.
