Most IPv6 implementation plans make use of both static IPv6 address configuration and dynamic configuration options. As is the case with IPv4, the plan assigns infrastructure devices with static addresses, with client hosts using one of the two dynamic methods for address assignment. IPv6 addressing includes many more options than IPv4, and as a result, many more config-uration options exist. A router interface can be configured with a static global unicast IPv6 address, either with or without using the EUI-64 option. Although less likely, a router could be configured to dynamically learn its IPv6 address with either stateful DHCP or stateless autoconfig. The router interface could be configured to either not use a global unicast address, instead relying solely on its link local address, or to borrow another interface’s address using the IPv6 unnumbered feature. Following Table summarizes the IPv6 configuration commands and their meanings.
This can be enabled on these devices only on the CLI, with the following command:
saleh->set envar ipv6=yes Then Reboot The Router
saleh-> set interface ethernet0/0 ipv6 mode router
saleh-> set interface ethernet0/0 ipv6 ip "ipv6-address/prefix"
