Configuring the FIB Entry Delivery Mode for Network Segment Routes
Usage Scenario
In the current FIB entry delivery mode, FIB entries for host routes and network segment routes are delivered to different modules by default, occupying resources of different modules. In real-world networks, there are often a large number of network segment routes, causing insufficient module resources. In this scenario, you can configure the FIB entry delivery mode of network segment routes as the extended mode. This mode ensures that FIB entries for network segment routes with the fixed mask length are delivered to the module where host routes reside, implementing flexible forwarding resource sharing and expanding network segment routing capability.
The CE12800E does not support this configuration.
After the FIB entry delivery mode of network segment routes is configured, you need to restart the switch to make the configuration take effect.
Pre-configuration Tasks
Before configuring the FIB entry delivery mode of network segment routes as the extended mode, you must run the set forward capability enhanced command to set the card interoperability mode to enhanced mode.
Procedure
- Run system-view
The system view is displayed.
- Run system resource fib ipv4 extend mask mask-length
The FIB entry delivery mode of network segment routes is configured as the extended mode.
By default, the FIB entry delivery mode of network segment routes is the standard mode.
- Run commit
The configuration is committed.
