Release Information

Statement introduced in Junos OS Release 9.6.

Statement introduced in Junos OS Release 10.4 for EX Series switches.

Description

Specify to send self-generated link-state advertisements (LSAs) with the DoNotAge bit set. As a result, self-originated LSAs are not reflooded every 30 minutes, as required by OSPF by default. An LSA is refreshed only when the content of the LSA changes, which reduces OSPF traffic overhead in stable topologies.

Required Privilege Level
