20.2.13 Configuring IS-IS Route Metric Type

IS-IS routing protocol has two styles of route metric:
Narrow: The value of route metric ranges from 1 to 63.
Wide: The value of route metric ranges from 1 to 16,777,215.
A router can choose either or both of the styles.
Perform the following configuration in IS-IS view.
Table 20-14 Configure the style for route metric values of IS-IS packets
Configure the style for route
metric values of IS-IS packets
Restore the default settings
By default, IS-IS only receives and sends the packets whose route metric is in narrow
style.

20.2.14 Setting IS-IS Link State Routing Cost

Users can configure the interface cost, namely, the default routing cost.
Perform the following configuration in interface view.
Table 20-15 Set IS-IS link state routing cost
Set the routing cost of the interface
Restore the default routing cost of the
interface
If the level is not specified, the default setting is Level-1 routing cost.
The value argument is configured according to the link state of the interface.
By default, the routing cost of IS-IS on an interface is 10.

20.2.15 Configuring IS-IS Timers

I. Setting the Hello packet broadcast interval
The IS-IS periodically sends the Hello packets from the interface and the routers
maintain the adjacency through the transmitting/receiving of the Hello packets The
Hello packet interval can be modified.
