Understanding IPv6
IPv6 Stateless Autoconfiguration and Duplicate Address Detection
The switch uses stateless autoconfiguration to manage link, subnet, and site addressing changes, such as
management of host and mobile IP addresses. A host autonomously configures its own link-local
address, and booting nodes send router solicitations to request router advertisements for configuring
interfaces.
For more information about autoconfiguration and duplicate address detection, see the "Implementing
IPv6 Addressing and Basic Connectivity" chapter of Cisco IOS IPv6 Configuration Library on
Cisco.com.
IPv6 Applications
The switch has IPv6 support for these applications:
•
•
•
•
•
For more information about managing these applications, see the "Managing Cisco IOS Applications
over IPv6" chapter and the "Implementing IPv6 Addressing and Basic Connectivity" chapter in the
Cisco IOS IPv6 Configuration Library on Cisco.com.
Dual IPv4 and IPv6 Protocol Stacks
You must use the dual IPv4 and IPv6 template to allocate ternary content addressable memory (TCAM)
usage to both IPv4 and IPv6 protocols.

Use the dual IPv4 and IPv6 switch database management (SDM) template to enable dual stack
environments (supporting both IPv4 and IPv6). For more information about the dual IPv4 and IPv6 SDM
template, see
