LDP ECMP Uniform Failover
RSVP LSP alone fails and the latter is not protected by RSVP FRR, the failure event will trigger
the re-resolution of the impacted FECs in the slow path.
When a multicast LDP (mLDP) FEC is resolved over ECMP links to the same downstream LDP
LSR, the PG-ID DOWN state will cause packets of the FEC resolved to the failed link to be
switched to another link using the linear FRR switchover procedures.
The LDP ECMP uniform failover is not supported in the following forwarding contexts:
•
•
•
Finally, note that the LDP ECMP uniform failover is only supported for a single LDP interface,
LDP next-hop, or peer failure event.
