Description
Enable indirectly connected next hops for route convergence. This statement is implemented on the Packet Forward Engine to speed up forwarding information base (FIB) updates. Configuring this statement significantly speeds convergence times. The only downside of configuring this statement is that some additional FIB memory overhead is required. Unless routes have an extremely high number of next hops, this increased memory usage should not be noticeable.
When virtual private LAN service (VPLS) is configured on the routing device, the
indirect-next-hopstatement is configurable at the[edit routing-options forwarding-table]hierarchy level. However, this configuration is not applicable to indirect nexthops specific to VPLS routing instances.By default, the Junos Trio Modular Port Concentrator (MPC) chipset on MX Series routers is enabled with indirectly connected next hops, and this cannot be disabled using the
no-indirect-next-hopstatement.By default, indirectly connected next hops are enabled on PTX Series routers.
Default
Disabled.
Options
indirect-next-hop—Enable indirectly connected next hops.
no-indirect-next-hop—Explicitly disable indirect next hops.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
Release Information
Statement introduced in Junos OS Release 8.2.
