DETAILED STEPS
Purpose
Command or Action
configure
Step 1
Enters interface configuration mode.
interface type interface-path-id
Example:
Step 2
RP/0/RP0/CPU0:router(config)# interface
GigabitEthernet 0/1/0/3
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.
Do one of the following:
Step 3
•
ipv4 address address mask
•
ipv6 address ipv6-prefix / prefix-length
[
eui-64
]
or
•
ipv6 address ipv6-address
{
/ prefix-length
|
link-local
}
Specifies an IPv6 network assigned to the interface and
enables IPv6 processing on the interface with the
eui-64
keyword.
•
ipv6 enable
Example:
or
RP/0/RP0/CPU0:router(config-if)# ipv4 address
10.0.1.3 255.255.255.0
Specifies an IPv6 address assigned to the interface and
enables IPv6 processing on the interface with the
link-local
keyword.
