Configuring BFD for LSPs

Network requirements
As shown in
21.1.1.0/24 to 1 1.1.1.0/24. Configure BFD for the LSPs to detect LSP failures.
Configuration procedure
Configure LDP sessions (see
1.
Enable BFD for LSPs:
2.
# Configure Switch A.
<SwitchA> system-view
[SwitchA] mpls lspv
[SwitchA -mpls-lspv] bfd enable 21.1.1.0 24
[SwitchA -mpls-lspv] quit
# Configure Switch C.
<SwitchC> system-view
[SwitchC] mpls lspv
[SwitchC-mpls-lspv] bfd enable 11.1.1.0 24
[SwitchC-mpls-lspv] quit
Verify the configuration:
3.
# Execute the display mpls lsp bfd command on Switch A and Switch C to view information about
the sessions established for the LSPs. Take Switch A as an example:
[SwitchA] display mpls lsp bfd
