The hold time specifies how long a neighbor should consider this router to be operative without receiving another hello packet. If the neighbor does not receive a hello packet from this router within the hold time, it marks the router as being unavailable. The default hold-time value is three times the default hello interval: 9 seconds for a DIS router and 27 seconds for a non-DIS router.
To modify the hold-time value on the local router, include the hold-time statement:
-
hold-time seconds;
