export-rib

 

Syntax

Hierarchy Level

Release Information

Statement introduced before Junos OS Release 7.4.

Description

Specify the name of the routing table from which Junos OS should export routing information. For any individual RIB group, only one table can be specified in the export-rib statement.

The export-rib statement specifies the source table from which routing information is advertised.

One common use of the export-rib statement is interdomain routing. The export RIB is the table used when BGP extracts routes to advertise to peers. In multicast interdomain routing, for example, the export RIB is likely to be inet.2.

Another use of export-rib is dynamic route leaking between the global routing table (inet.0) and a VRF routing table (instance.inet.0). For example, you can use a RIB group to copy routes learned in the VRF into the global routing table, inet.0, or copy routes learned in inet.0 into a VRF. You define the use of this RIB group in the VRF’s BGP configuration. In a routing policy you can do dynamic filtering of routes. For instance, you can use an import policy to only copy routes with certain communities into the global routing table.

For example:
