7.2.4 (Optional) Configuring the IPv4 IS-IS Interfaces

Configuring the IS-IS interface costs can control IS-IS route selection.
Context
The costs of IS-IS interfaces can be determined in the following modes in descending order by
priority:
l
l
l
If none of the preceding configurations is performed, the default cost of an IS-IS interface is 10,
and the default cost style is narrow.
Procedure
l
Issue 02 (2014-09-30)
(Optional) Configure a delay for the IS-IS neighbor relationship establishment.
Run:
isis delay-peer track last-peer-expired [ delay-time delay-interval ]
A delay is configured for the IS-IS neighbor relationship establishment.
By default, delay-interval is 60s.
If a new delay-interval is configured and it is less than the remaining time of the ongoing
delay, the new delay-interval takes effect immediately; if the new delay-interval is greater
than the remaining time of the ongoing delay, the ongoing delay continues until the new
delay-interval takes effect at the next delay.
Interface cost: is configured for a specified interface.
Global cost: is configured for all interfaces.
Automatically calculated cost: is automatically calculated based on the interface
bandwidth.
Configure the IS-IS cost type.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
cost-style { narrow | wide | wide-compatible | { { narrow-compatible |
compatible } [ relax-spf-limit ] } }
The IS-IS cost type is configured.
The cost range of an interface and a route received by the interface vary with the cost type.
– If the cost type is narrow, the cost of an interface ranges from 1 to 63. The maximum
cost of a route received by the interface is 1023.
