An IS-IS PPP interface can have a peer on a different network. To establish neighbor relationship with the

peer, you must disable source address check for hello packets on the PPP interface by using the isis

peer-ip-ignore command.

[Sysname] interface serial 2/0

[Sysname-Serial2/0] isis peer-ip-ignore

isis silent

Use isis silent to disable the interface from sending and receiving IS-IS packets.

Use undo isis silent to restore the default.
