avaya.com 1. Overview This document is intended to show the various supported topologies and features for switch clustering on the Virtual Services Platform 9000 and Ethernet Routing Switch portfolio. With each topology, please take note to where bridging, routing, and multicast are configured as support will vary between switch types. The topologies shown in each example do not indicate the scalability of the solution. They are only representative to provide the topology architecture.
