Collaboration Deployment Models for IPv6 Overview
This chapter describes the deployment models you can use with IPv6 in Cisco Collaboration networks. Cisco Unified Communications Manager (Unified CM) supports the following traditional IPv4 deployment model examples:
-
Single-site deployments
-
Multi-site WAN deployments with distributed call processing
-
Multi-site deployments with centralized call processing and Cisco Unified Survivable Remote Site Telephony (Unified SRST)
With all of these deployment models, IPv6 endpoints should be configured as IPv6 with a preference of IPv6 for signaling and media. This configuration maximizes the amount of IPv6 traffic with the use of media termination points (MTPs) for conversions between IPv4 and IPv6.
