The irb asymmetric command enables the asymmetric mode for IRB routes.
The undo irb asymmetric command restores the default configuration.
By default, the asymmetric mode is disabled for IRB routes.
Usage Scenario
By default, a device generates an IP prefix route based on the IP address in an IRB route that it has received from a BGP EVPN peer. IP prefix routes can be used for Layer 3 traffic forwarding. If Layer 2 forwarding is required, run the irb asymmetric command to enable the asymmetric mode for IRB routes. Specifically, after this configuration is performed, the device does not generate IP prefix routes after receiving IRB routes.
