Disabling And Reenabling Incremental Spf; Configuring Ospf Traps - Juniper IGP - CONFIGURATION GUIDE V11.1.X Configuration Manual

Disabling and Reenabling Incremental SPF

By default, when changes occur to a type 5 or type 7 LSA, OSPF recalculates new,
loop-free routes for only the LSAs that change. When a subset of LSAs in the external
link-state database change, a full recalculation is not necessary. However, through
the CLI, you can disable incremental SPF so the router can perform a full SPF on all
external LSAs in the link-state database.

Configuring OSPF Traps

You can use the traps command to specify OSPF traps. This command enables you
to specify all or any number of the following trap settings:
traps
Use to disable incremental external SPF on the router. When issued, this
command results in a full SPF when an event occurs to trigger an external SPF.
Example
host1(config-router)#disable-incremental-external-spf
Use the no version to reenable incremental SPF on this router.
