Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
Specifies an IPv6 address assigned to the interface and enables IPv6
processing on the interface with the link-local keyword.
Example:
RP/0/RSP0/CPU0:router(config-if)# ipv4
address 10.0.1.3 255.255.255.0
or
Automatically configures an IPv6 link-local address on the interface
while also enabling the interface for IPv6 processing.
or
RP/0/RSP0/CPU0:router(config-if)# ipv6
address 3ffe:1234:c18:1::/64 eui-64
•
The link-local address can be used only to communicate with
nodes on the same link.
RP/0/RSP0/CPU0:router(config-if)# ipv6
address FE80::260:3EFF:FE11:6770
link-local
•
Specifying the ipv6 address ipv6-prefix / prefix-length interface
configuration command without the eui-64 keyword configures
site-local and global IPv6 addresses.
RP/0/RSP0/CPU0:router(config-if)# ipv6
enable
or
•
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.
exit
Example:
RP/0/RSP0/CPU0:router(config-if)# exit
Step 4
Enables IS-IS routing for the specified routing instance, and places the
router in router configuration mode.
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router
isis isp
Step 5
•
By default, all IS-IS instances are Level 1 and Level 2. You can
change the level of routing to be performed by a particular routing
instance by using the is-type command.
Configures NETs for the routing instance.
net network-entity-title
Step 6
Example:
RP/0/RSP0/CPU0:router(config-isis)# net
47.0004.004d.0001.0001.0c11.1110.00
•
Specify a NET for each routing instance if you are configuring
multi-instance IS-IS. You can specify a name for a NET and for
an address.
•
This example configures a router with area ID 47.0004.004d.0001
and system ID 0001.0c11.1110.00.
•
To specify more than one area address, specify additional NETs.
Although the area address portion of the NET differs, the system
ID portion of the NET must match exactly for all of the configured
items.
