DES-7200 Configuration Guide Chapter 3 BFD Configuration
3-10
Caution
BFD for VRRP+ is supported in release firmware v10.4(3).
3.2.10 BFD supports to change the
State of Layer3 Interfaces
BFD supports to change the state of layer-3 interface. In configuration mode,
execute "bfd bind peer-ip" to detect the directly connected address of the
specified layer-3 interface. The BFD session state established by this CLI
command will generate the BFD state of the corresponding interface, such as
BFD-DOWN/BFD-UP. In various types of FRR, BFD is used to detect interface
state and perform fast FRR switchover.
Caution
Association between BFD and layer-3 interface is supported in release
firmware v10.4(3).
3.2.11 BFD for MPLS-LSP
BFD for MPLS mainly refers to the case that LSP (Label Switched Path) uses
BFD to carry out quick neighbor detection. The detection modes supported
include:
1. Configure BFD for detecting static LSP;
2. Configure BFD for detecting the LSP generated by LDP;
3. Configure BFD for detecting backward LSP with IP
Caution
BFD for MPLS-LSP is supported in release firmware v10.4(3).
3.2.12 BFD for VRF
