Release Information

Statement introduced before Junos OS Release 7.4.

Description

Group one or more routing tables to form a routing table group. A routing protocol can import routes into all the routing tables in the group and can export routes from a single routing table.

Each routing table group must contain one or more routing tables that Junos OS uses when importing routes (specified in the import-rib statement) and optionally can contain one routing table group that Junos OS uses when exporting routes to the routing protocols (specified in the export-rib statement).

The first routing table you specify is the primary routing table, and any additional routing tables are the secondary routing tables.

The primary routing table determines the address family of the routing table group. To configure an IP version 4 (IPv4) routing table group, specify inet.0 as the primary routing table. To configure an IP version 6 (IPv6) routing table group, specify inet6.0 as the primary routing table. If you configure an IPv6 routing table group, the primary and all secondary routing tables must be IPv6 routing tables (inet6.x).

In Junos OS Release 9.5 and later, you can include both IPv4 and IPv6 routing tables in an IPv4 import routing table group using the import-rib statement. In releases prior to Junos OS Release 9.5, you can only include either IPv4 or IPv6 routing tables in the same import-rib statement. The ability to configure an import routing table group with both IPv4 and IPv6 routing tables enables you, for example, to populate the inet6.3 routing table with IPv6 addresses that are compatible with IPv4. Specify inet.0 as the primary routing table, and specify inet6.3 as a secondary routing table.

Note

On EX Series switches, only dynamically learned routes can be imported from one routing table group to another.

Note

If you configure an import routing table group that includes both IPv4 and IPv6 routing tables, any corresponding export routing table group must include only IPv4 routing tables.

If you have configured a routing table, configure the OSPF primary instance at the [edit protocols ospf] hierarchy level with the statements needed for your network so that routes are installed in inet.0 and in the forwarding table. Make sure to include the routing table group. For more information, see Example: Configuring Multiple Routing Instances of OSPF.

After specifying the routing table from which to import routes, you can apply one or more policies to control which routes are installed in the routing table group. To apply a policy to routes being imported into the routing table group, include the import-policy statement.

Options

group-name—Name of the routing table group. The name must start with a letter and can include letters, numbers, and hyphens.

The remaining statements are explained separately. See CLI Explorer.
