The silent-interface command is only used to restrain the IS-IS packets not to be sent
on the interface, but the interface routes still can be sent from other interfaces.
Example
# Prohibit the IS-IS packets to be transmitted via Interface Ethernet1/0/0.

Parameter
number: Interval for actively releasing CPU in route calculation. It is in pieces, ranging
from 1000 to 50000. By default, the value is 5000.
Description
Use the spf-delay-interval command to configure the interval for actively releasing
CPU in the SPF calculation.
Use the undo spf-delay-interval command to restore the default setting.
When there are a large number of routes in the routing table, this command can be
used to set that CPU resources are released automatically after a certain number of
routes are processed. The unprocessed routes will be processed in one second.
The value of the parameter number can be adjusted according to the capacity of the
routing table. If the spf-slice-size command is also configured, the SPF calculation will
be paused when any setting item is met.
By default, CPU is released once when every 5000 pieces of routes are processed.
Related command: spf-slice-size.
Example
# Set IS-IS to release CPU once after processing every 3000 pieces of routes.
