Configuring The Minimum Lsr Receiving Interval; Configuring The Minimum Lsr Refresh Interval; Configuring The Fspf Cost For An Interface - HP 5920 series Configuration Manual

Configuring the minimum LSR receiving interval

The minimum LSR receiving interval specifies the time between receiving LSRs in a VSAN. Any LSR
instances of the same LSR received within this time are dropped. This helps avoid frequent SPF
calculations caused by LSDB updating.
To configure the minimum LSR receiving interval:
Step
1. Enter system view.
2. Enter VSAN view.
3. Configure the minimum
LSR receiving interval.

Configuring the minimum LSR refresh interval

The minimum LSR refresh interval specifies the interval at which LSRs are refreshed. To reduce SPF
calculations and LSR flooding in a fabric caused by frequent LSR refreshing, the switch cannot refresh
local LSRs within this interval.
To configure the minimum LSR refresh interval:
Step
1. Enter system view.
2. Enter VSAN view.
3. Configure the minimum
LSR refresh interval.

Configuring the FSPF cost for an interface

Each link has a different cost. The route selection algorithm uses this value to determine the best route. The
smaller the interface FSPF cost, the smaller the link cost.
To configure the interface FSPF cost:
Step
1. Enter system view.
2. Enter VFC interface view.
3. Configure the FSPF cost for
the VFC interface in a
specified VSAN.
