Stateless Autoconfiguration

The final example in this section demonstrates stateless autoconfiguration using two routers, R2 and R3. In Example 3-5, R2’s Fa0/1 configuration will be changed, using the ipv6 address autoconfig subcommand on that interface. This tells R2 to use the stateless autoconfig process, with R2 learning its prefix from Router R3. R2 then builds the rest of its IPv6 address using EUI-64.
