10.7.6 Checking the Configuration

After filters are applied to imported routes, you can check information about the routing table
of each protocol.
Prerequisites
The configurations for applying filters to imported routes are complete.

10.8 Controlling the Valid Time of the Routing policy

To ensure network stability, you need to configure the delay for applying a routing policy when
modifying the routing policy.

10.8.1 Establishing the Configuration Task

Before configuring the delay for applying a routing policy, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you complete the configuration task quickly and accurately.
Applicable Environment
In actual applications, when the configurations of multiple cooperative routing polices change,
the Routing Management Module (RM) immediately notifies related protocols to apply a new
routing policy, after the configuration of the routing policy is complete. An incomplete routing
policy causes route flapping, instability of the network, and a waste of time during packet
processing.
The S6700 provides the following rules for processing changes of a routing policy:

Run the display rip process-id route command to check information about the RIP routing
table.
Run the display ospf [ process-id ] routing command to check information about the OSPF
routing table.
Run the display isis [ process-id ] route command to check information about the ISIS
routing table.
Run the display bgp routing-table command to check information about the BGP routing
table.
Run the display ip routing-table command to check information about the public IPv4
routing table.
Run the display ip routing-table command on the neighboring switch. You can find that
the routes that meet the matching rules on the neighboring switch are filtered or the actions
defined by the apply clauses are performed.
By default, the RM immediately notifies the protocol of applying the new policy when the
routing policy changes.
If the valid time of the routing policy is configured, when the commands used to configure
the routing policy change, the RM does not notify various protocols of immediately
