In the following case, the CPE router requests prefix from the PE router. The PE router
chooses prefix (2001:1::/64) for delegation, and responds with the prefix to the requesting
CPE router. The CPE router subnets the prefix and assigns the longer prefixes to links in the
user's network. The CPE router is then responsible to assign the 2001:1:1::/96 to one user's
network and 2001:1:2::/96 to another user's network.
