III. Configuring SPF to release CPU resources automatically
In IS-IS, SPF calculation may occupy system resources for a long time and slow down
console response. To avoid this, you can configure SPF to automatically release CPU
resources each time a specified number of routes are processed and continue to
calculate the remaining routes after one second.
Follow these steps to configure SPF to release CPU resources automatically:
Enter system view
Enter IS-IS view
Configure the interval at
which SPF releases CPU
resources

5.3.24 Enabling/Disabling Packet Transmission Through an Interface

To prevent IS-IS routing information from being accessed by a router on another
network, use the silent-interface command to configure the VLAN interface
containing the network segment to receive, but not to send, IS-IS packets.
Follow these steps to enable/disable packet transmission through an interface:
Enter system view
Enter IS-IS view
Disable an interface from
sending IS-IS packets
