Implementing IS-IS
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
Example:
RP/0/RSP0/CPU0:router(config-if)# ipv4
address 10.0.1.3 255.255.255.0
or
RP/0/RSP0/CPU0:router(config-if)# ipv6
address 3ffe:1234:c18:1::/64 eui-64
RP/0/RSP0/CPU0:router(config-if)# ipv6
address FE80::260:3EFF:FE11:6770
link-local
RP/0/RSP0/CPU0:router(config-if)# ipv6
enable
or
Step 4
exit
Example:
RP/0/RSP0/CPU0:router(config-if)# exit
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.
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.
Exits interface configuration mode, and returns the router to global
configuration mode.
