Parameters
ipv6-address/prefix-length: Specifies an IPv6 address and its prefix length. The ipv6-address and
prefix-length arguments jointly specify the prefix of an EUI-64 IPv6 address.
Usage guidelines
An EUI-64 IPv6 address is generated based on the specified prefix and the automatically generated
interface identifier and is displayed by using the display ipv6 interface command.
The prefix length of an EUI-64 IPv6 address cannot be greater than 64.
Examples
# Configure an EUI-64 IPv6 address for Ethernet 1/1. The prefix length of the address is the same as that
of 2001::1/64, and the interface ID is generated based on the MAC address of the device.

Usage guidelines
Manual assignment takes precedence over automatic generation. If you first adopt automatic generation
and then manual assignment, the manually assigned link-local address overwrites the automatically
