The auto-frr command enables BGP Auto fast reroute (FRR).
The undo auto-frr command restores the default configuration.
By default, BGP Auto FRR is disabled.
Implementation Procedure
If both the ip frr and auto-frr commands are configured, the auto-frr command takes precedence over the ip frr command.
Precautions
Using both BGP Auto FRR and BFD is recommended. They can rapidly detect a link fault and switch traffic to a backup link if a fault occurs.
