When the isis peer-ip-check command is configured, an IS-IS PPP interface can establish a neighbor
relationship only with a peer on the same network.
Examples
# Enable source address check for hello packets on interface Serial 2/1/0.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] isis peer-ip-check
isis prefix-suppression
Use isis prefix-suppression to enable prefix suppression on an interface.
Use undo isis prefix-suppression to restore the default.

Usage guidelines
Use this command to disable an interface from advertising its prefix in LSPs. This enhances network
security by preventing IP routing to the interval nodes and speeds up network convergence.
This command is also applicable to the secondary IP address of the interface.
Examples
# Enable prefix suppression on interface GigabitEthernet 2/1/1.
<Sysname> system-view
