Link State Record Defaults
Each time a new switch enters the fabric, a link state record (LSR) is sent to the neighboring switches,
and then flooded throughout the fabric.

Purpose
Configures the hold time between two route
computations in milliseconds (ms) for the entire
VSAN. The default value is 0.
Note
If the specified time is shorter, the
routing is faster. However, the processor
consumption increases accordingly.
Configures the autonomous region for this
VSAN and specifies the region ID (7).
Purpose
Enters configuration mode.
Deletes the FSPF configuration for VSAN 3.
Purpose
