routing-table rib-only route-filter (BGP-IPv4 unicast address family view)

Function

The routing-table rib-only route-filter command prohibits BGP routes matching a filtering policy from being added to the IP routing table.

The undo routing-table rib-only route-filter command restores the default configuration.

By default, the preferred BGP routes are added to the IP routing table.

Usage Guidelines

Usage Scenario

If a route reflector (RR) is used and preferred BGP routes do not need to be used during the forwarding, the routing-table rib-only command can be used to make BGP routes unable to be added to the IP routing table or the forwarding layer. This improves forwarding efficiency and the system capacity.

Configuration Impact

After the routing-table rib-only command is run, the routes preferred by BGP are not added to the IP routing table.

Precautions

The routing-table rib-only command and the active-route-advertise command are mutually exclusive.
