Supported IPv6 Host Functions and Unicast Routing Features
Table 39-1 shows the supported IPv6 features on each switch.
Understanding IPv6
The IPv6 architecture allows existing IPv4 users to move to IPv6 and provides services such as
end-to-end security, quality of service (QoS), and globally unique addresses. The IPv6 address space
reduces the need for private addresses and the use of Network Address Translation (NAT) processing by
border routers at the edge of networks. IPv6 provides newer unicast methods, introduces hexadecimal
values into the IP address, and uses colons (:) instead of periods (.) as delimiters.
