Enabling IGP Shortcuts
IGP shortcuts are supported for both IS-IS and OSPF. A link-state protocol is required for IGP shortcuts. Shortcuts are disabled by default. For information about enabling IGP shortcuts for IS-IS and OSPF, see the Junos Routing Protocols Configuration Guide. You can enable IGP shortcuts on a per-router basis; you do not need to enable shortcuts globally. A router’s shortcut computation does not depend on another router performing similar computations, and shortcuts performed by other routers are irrelevant.
