IPv6 Support in Avi Vantage
With the emerging utility of IPv6 in traditional networks, web applications are adapting to support both IPv4 and IPv6 requests. The network infrastructure is expected to process client requests originating from IPv4 and/or IPv6 based devices. Server clustering along with server load balancing has emerged as a promising technique to build scalable web servers.
Starting with 18.1.1 release, Avi Vantage provides full IPv6, and dual-stack IPv4 and IPv6 connectivity to the load balancing network without relying on any tunnelling solutions. Figure 1 refers to generic use cases for IPv6 support.
Figure 1. Use case scenarios
IPv6 is supported on baremetal, VMware vCenter, Linux server cloud, and OpenStack clouds.
