Setting The Lsr Retransmission Interval For An Interface; Disabling Fspf For An Interface; Configuring Fspf Gr - HP FlexFabric 5700 Series Configuration Manual

NOTE:
The configured dead interval must be greater than the hello interval and must be the same at the two ends
of the link.
To set the dead interval for an interface:
Step
1. Enter system view.
2. Enter VFC interface view.
3. Set the dead interval for the
interface in a VSAN.

Setting the LSR retransmission interval for an interface

The LSR retransmission interval specifies the time to wait for an LSR acknowledgment from the neighbor
before retransmitting the LSR.
To set the LSR retransmission interval for an interface:
Step
