Permitting The Bfd To Modify The Pst - Huawei NetEngine80E Configuration Manual - Reliability

HUAWEI NetEngine80E/40E Router
Configuration Guide - Reliability
Applicable Environment
If the BFD can modify the Port State Table (PST), it modifies the corresponding entry in the
PST when it detects that an interface is Down. Through the PST, other upper application
protocols can acknowledge whether the interface has a fault.
Currently, for the NE80E/40E, LDP FRR and IP FRR based on BFD detection need to know
the BFD detection result through the PST.
You do not need to run the process-pst command on the applications that do not learn the BFD
results through the PST.
Pre-configuration Tasks
Before configuring the BFD to modify the PST, complete the task of
hop
Data Preparation
To configure the BFD to modify the PST, you need the following data.

NOTE
l For the LDP FRR, refer to chapter "MPLS Basic Configuration"in the HUAWEI NetEngine80E/40E
Router Configuration Guide - MPLS.
l IP FRR works for the public network and for the private network. For information about the IP FRR
for the public network, refer to Chapter 10 "Routing Policy Configuration" in the HUAWEI
NetEngine80E/40E Router Configuration Guide - IP Routing.
l For information about the IP FRR for the private network, refer to Chapter 4 "BGP MPLS IP VPN
