calculated differently for each IS-IS interface. The default routing metric in this case is
the reference bandwidth divided by the bandwidth of the particular interface.
For example, if you set the IS-IS reference bandwidth to 50,000,000, the default metric
for a 10-Mbps interface is calculated as 5. Interfaces with lower bandwidths have higher
default metrics than this interface. Similarly, links with higher bandwidths have lower
default metrics than this interface.
Use to set a reference bandwidth from which a default metric can be calculated by
IS-IS for interfaces without a configured metric.
Example
host1(config-router)#reference-bandwidth 100000000
Use the no version to remove the reference bandwidth. When you do so, the default
metric reverts to 10.
See reference-bandwidth
You can set the advertised complete sequence number PDU (CSNP) interval for an IS-IS
interface.
Use to configure the isis csnp-interval level for a specified interface. The level can be
configured independently for level 1 and level 2.
For LAN interfaces: the default value is 10 seconds, which you probably do not need
to change. For WAN interfaces: the default value is 0 seconds or disabled.
On point-to-point subinterfaces use isis csnp-interval with the isis mesh-group
command.
Completed sequence number PDUs are sent by the designated router to maintain
database synchronization.
Example
host1(config-if)#isis csnp-interval 30 level-1
Use the no version to restore the default value.

You can set the hello interval and the hello multiplier for IS-IS hello packets.
