Issue 02 (2014-09-30)
Create an IS-IS process and configure the NET of a device, enable IPv6 for the process.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
An IS-IS process is created, and the IS-IS process view is displayed.
The process-id parameter specifies the ID of an IS-IS process. The default value of
process-id is 1. To associate an IS-IS process with a VPN instance, run the isis process-
id vpn-instance vpn-instance-name command.
3. Run:
network-entity net
or
network-entity area area-id auto-systemid lsr-id
A NET is configured.
NOTICE
Configuring loopback interface addresses based on NETs is recommended to ensures
that a NET is unique on the network. If NETs are not unique, route flapping will easily
occur.
System ID used in IS-IS can be obtained in the following way: extend each part of the
IP address to 3 bits, add 0 to the front of any part that is shorter than 3 bits, divide the
extended address into three parts, with each part consisting of four decimal digits, and
the reconstructed address is the system ID.
Area addresses of NETs are checked when Level-1 IS-IS neighbor relationships are
being established, but not checked when Level-2 IS-IS neighbor relationships are
being established. Level-1 IS-IS neighbor relationships can be established only if area
addresses of NETs are the same.
4. Run:
ipv6 enable
The IPv6 of IS-IS process is enabled.
(Optional) Configure the level of a device.
1. Run:
is-level { level-1 | level-1-2 | level-2 }
The level of the router is configured.
(Optional) Configure IS-IS host name mapping.
1. Run:
is-name symbolic-name
