Configuring Spf Parameters - HP 4800G Series Configuration Manual

To avoid this, you can configure some interfaces as a mesh group or/and configure the blocked
interfaces.
After receiving an LSP, a member interface in a mesh group floods it out the interfaces that does
not belong to the mesh group.
If an interface is blocked, it does not send LSPs unless the neighbor sends LSP requests to it.
Before configuring this task, you need to consider redundancy for interfaces to avoid the fact that LSP
packets cannot be flooded due to link failures.
Follow these steps to add an interface into a mesh group and block an interface:
To do...
Enter system view
Enter interface view
Add the interface to a mesh
group
Block the interface
The mesh group feature takes effect only on P2P interfaces.

Configuring SPF Parameters

When the LSDB changes on a router, a route calculation starts. Frequent route calculations consume a
lot of system resources, while route calculations at a proper interval improve efficiency. You can set an
appropriate interval for SPF calculations as needed.
Follow these steps to configure the SPF parameters:
Use the command...
system-view
interface interface-type
interface-number
isis mesh-group
mesh-group-number
isis mesh-group
mesh-blocked
1-28

––
Required to choose either.
By default, the interface neither
belongs to any mesh group nor
is blocked.
