Configuring Spf Parameters; Assigning A High Priority To Is-Is Routes - HPE FlexNetwork HSR6800 Configuration Manual

Before you configure this task, you must consider redundancy for interfaces in case that LSP
packets cannot be flooded due to link failures.
To add an interface into a mesh group and block an interface:
Step
Enter system view.
1.
Enter interface view.
2.
Add the interface to a mesh
3.
group, or block the interface.

Configuring SPF parameters

When the LSDB changes on a router, a route calculation starts. Frequent route calculations
consume a lot of system resources. You can set an appropriate interval for SPF calculations to
improve efficiency.
To configure the SPF parameters:
Step
Enter system view.
1.
Enter IS-IS view.
2.
Configure the SPF
3.
calculation interval.

Assigning a high priority to IS-IS routes

An IS-IS topology change causes network convergence. By assigning a high priority to specific IS-IS
routes, you can achieve faster network convergence.
To assign a high priority to IS-IS routes:
Step
Enter system view.
1.
Enter IS-IS view.
2.

Use either method.
By default, the interface neither
belongs to any mesh group nor is
it blocked.
The mesh group feature takes
effect only on P2P interfaces.
