DETAILED STEPS
Command or Action
Step 1 configure
Step 2 interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config)# interface
GigabitEthernet 0/1/0/3
Step 3 Do one of the following:
• ipv4 address address mask
• ipv6 address ipv6-prefix / prefix-length
[ eui-64 ]
• ipv6 address ipv6-address { /
prefix-length | link-local }
• ipv6 enable

• ipv4 address address mask
• ipv6 address ipv6-prefix / prefix-length [ eui-64 ]
• ipv6 address ipv6-address { / prefix-length | link-local }
• ipv6 enable
Purpose
Enters interface configuration mode.
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 with the eui-64 keyword.
