OSPFv3 Commands 1209
Syntax
nsf [ietf ] restart-interval seconds
no nsf [ietf] restart-interval
• ietf — This keyword is used to distinguish the IETF standard
implementation of graceful restart from other implementations. Since the
IETF implementation is the only one supported, this keyword is optional.
•
seconds — The number of seconds that the restarting router asks its
neighbors to wait before exiting helper mode. The restarting router
includes the restart interval in its grace LSAs (range 1–1800 seconds).
Default Configuration
The default restart interval is 120 seconds.
Command Mode
Router OSPFv3 Configuration mode
User Guidelines
The grace period must be set long enough to allow the restarting router to
reestablish all of its adjacencies and complete a full database exchange with
each of those neighbors.
passive-interface
Use the passive-interface command to set the interface or tunnel as passive.
It overrides the global passive mode that is currently effective on the interface
or tunnel. Use the “no” form of this command to set the interface or tunnel
as non-passive.
Syntax
passive-interface {vlan vlan-id | tunnel tunnel-id }
no passive-interface {vlan
vlan-id | tunnel tunnel-id }
• vlan-id — The vlan number
•
tunnel-id — Tunnel identifier. (Range: 0–7)
