Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VFC interface view. interface vfc interface-number N/A
3. Configure the dead interval for
the interface in a specified
VSAN.
fspf dead-interval value vsan
vsan-id
The default setting is 80 seconds.
Configuring the LSR retransmission interval for interfaces
The LSR retransmission interval specifies the time to wait for an LSR acknowledgement from the neighbor
before retransmitting the LSR.
To configure the LSR retransmission interval:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VFC interface view. interface vfc interface-number N/A
3. Configure the LSR retransmission
interval for the interface in a
specified VSAN.
fspf retransmit-interval value
vsan vsan-id
The default setting is 5 seconds.
Disabling FSPF for an interface
With FSPF enabled, an interface can participate in SPF calculation. To avoid SPF calculations on an
interface, disable FSPF on the interface.
To disable FSPF on an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VFC interface view. interface vfc interface-number N/A
3. Disable FSPF for the interface in
a specific VSAN.
fspf silent vsan vsan-id
By default, FSPF is enabled on a VFC
interface.
Configuring FSPF GR
FSPF Graceful Restart (GR) enables nonstop forwarding of traffic by backing up FSPF configuration
information during a protocol restart (for example, the FSPF process restart triggered by the process
command) or active/standby switchover.
GR involves the following roles:
• GR restarter—GR-capable device where a protocol restart or active/standby switchover occurs
• GR helper—The GR restarter's neighboring device that assists in the GR process
