Defines the IPv4 address for the interface.
• An IP address is required on all interfaces in an area
enabled for IS-IS if any one interface is configured for
IS-IS routing.
or
Specifies an IPv6 network assigned to the interface and
enables IPv6 processing on the interface.
or
Specifies an IPv6 address assigned to the interface and
enables IPv6 processing on the interface.
or
Automatically configures an IPv6 link-local address on the
interface while also enabling the interface for IPv6
processing.
• The link-local address can be used to communicate
only with nodes on the same link.
• Specifying the ipv6 address ipv6-prefix/prefix-length
interface configuration command without the eui-64
keyword configures site-local and global IPv6
addresses.
• Specifying the ipv6 address ipv6-prefix/prefix-length
command with the eui-64 keyword configures
site-local and global IPv6 addresses with an interface
ID in the low-order 64 bits of the IPv6 address. Only the
64-bit network prefix for the address needs to be
specified; the last 64 bits are automatically computed
from the interface ID.
• Specifying the ipv6 address command with the
link-local keyword configures a link-local address on
the interface that is used instead of the link-local
address that is automatically configured when IPv6 is
enabled on the interface.
