The packet loss-free MPLS ECMP switchback can be enabled.
In an L3VPN over BGP over TE or IP over BGP over TE scenario, after an MPLS TE tunnel is configured, the mpls load-balance wtr command is run in the system view to prevent packet loss during an MPLS ECMP switchback and set a switchback WTR time.
The system view is displayed.
The delay time is configured for MPLS ECMP switchback.
