Cisco NCS 5500 Series

DETAILED STEPS
Step 1 configure
Step 2 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config)# interface HundredGigE 0/1/0/3
Enters interface configuration mode.
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
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.0.1.3 255.255.255.0
or
RP/0/RP0/CPU0:router(config-if)# ipv6 address 3ffe:1234:c18:1::/64 eui-64
RP/0/RP0/CPU0:router(config-if)# ipv6 address FE80::260:3EFF:FE11:6770 link-local
RP/0/RP0/CPU0:router(config-if)# ipv6 enable
or
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.
or
Specifies an IPv6 address assigned to the interface and enables IPv6 processing on the interface with the link-local
keyword.
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 only to communicate 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.
