27.4 ipv6 address eui-64
Use the ipv6 address eui-64 command in Interface Configuration mode to
configure a global unicast IPv6 address for an interface and enables IPv6
processing on the interface using an EUI-64 interface ID in the low order 64 bits of
the address. To remove the address from the interface, use the no form of this
command.
Syntax

ipv6-prefix / prefix-length eui-64
no ipv6 address [
ipv6-prefix / prefix-length eui-64]

interface. This argument must be in the form documented in RFC4293
where the address is specified in hexadecimal using 16-bit values between
colons.
• prefix-length —The length of the IPv6 prefix. A decimal value that indicates
how many of the high-order contiguous bits of the address comprise the
prefix (the network portion of the address). A slash mark must precede the
decimal value.
