ip forwarding converge normal
Function
The ip forwarding converge normal command disables the device to perform Layer 2 forwarding for IP traffic during ring network switchover.
The undo ip forwarding converge command enables the device from performing Layer 2 forwarding for IP traffic during ring network switchover.
By default, the device is enabled from performing Layer 2 forwarding for IP traffic during ring network switchover.
Only the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
Usage Guidelines
Usage Scenario
When the device deployed with the ring network protocols (STP, RSTP, MSTP, SEP, ERPS, RRPP, VBST, and Smart Link) performs link switchover due to a link fault, the ARP entries need to be learned again. This deteriorates the Layer 3 convergence performance of IP traffic. If the device is enabled to perform Layer 2 forwarding for IP traffic during the switchover, the convergence performance can be improved. By default, the device is enabled from performing Layer 2 forwarding for IP traffic during ring network switchover.
Precautions
After the device is enabled to perform Layer 2 forwarding for IP traffic, it will forward the IP traffic in broadcast mode during ring network switchover. Therefore, the IP traffic increases within a short time.
