ECMP routes.

By default, the maximum
number of ECMP routes is 8.
Enabling the enhanced ECMP mode
When one or multiple ECMP routes fail, the default ECMP mode enables the device to reallocate all
traffic to the remaining routes.
The enhanced ECMP mode enables the device to reallocate only the traffic of the failed routes to the
remaining routes, which ensures forwarding continuity.
This configuration takes effect at reboot. Make sure the reboot does not impact your network.
To enable the IPv4 and IPv6 enhanced ECMP mode:
1. Enter system view.

2. Enable the IPv4 and IPv6
enhanced ECMP mode.

By default, the IPv4 and IPv6
enhanced ECMP mode is
disabled.
Configuring RIB NSR
Use this feature with protocol GR or NSR to avoid route timeouts and traffic interruption.
When an active/standby switchover occurs, nonstop routing (NSR) backs up routing information
from the active process to the standby process to avoid routing flapping and ensure forwarding
continuity.
RIB NSR provides faster route convergence than protocol NSR during an active/standby switchover.
Configuring IPv4 RIB NSR
1. Enter system view.
