addresses for the destination host name www.a.com from a DNS server. The DNS server replies with all
available addresses (both IPv4 and IPv6 addresses) for www.a.com. The application chooses an
address—in most cases, IPv6 addresses are the default choice—and connects the source node to the
destination using the IPv6 protocol stack.

Configuring Basic Connectivity for IPv6

The tasks in this section explain how to implement IPv6 basic connectivity. Each task in the list is
identified as either required or optional. This section includes the following topics:
•
•
•
•

Configuring IPv6 Addressing and Enabling IPv6 Routing

This task explains how to assign IPv6 addresses to individual router interfaces and enable the processing
of IPv6 traffic. By default, IPv6 addresses are not configured and IPv6 processing is disabled.
You can configure IPv6 addresses on the following interface types:
•
•
•
•
The ipv6-address argument in the ipv6 address command must be in the form documented in RFC 2373,
Note
where the address is specified in hexadecimal using 16-bit values between colons.
The ipv6-prefix argument in the ipv6 address command must be in the form documented in RFC 2373,
where the address is specified in hexadecimal using 16-bit values between colons.
