Release Information

Statement introduced before JUNOS Release 7.4.

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Description

Configure statically configured routes to be deleted from or retained in the forwarding table when the routing protocol process shuts down normally:

  • retain—Have a static route remain in the forwarding table when the routing protocol process shuts down normally. Doing this greatly reduces the time required to restart a system that has a large number of routes in its routing table.
  • no-retain—Delete statically configured routes from the forwarding table when the routing protocol process shuts down normally.

Default

no-retain
