Enabling the Capability of Dynamically Creating BFD Sessions on the Ingress

You can enable the ingress node to dynamically create BFD sessions on a TE tunnel either globally or on a specified tunnel interface.

Context

Perform either of the following operations:

Enable MPLS TE BFD globally if most TE tunnels on the ingress need to dynamically create BFD sessions.
Enable MPLS TE BFD on a tunnel interface if some TE tunnels on the ingress need to dynamically create BFD sessions.

Procedure

Enable MPLS TE BFD globally on the ingress.
1. Run system-view
  The system view is displayed.
2. Run mpls
  The MPLS view is displayed.
3. Run mpls te bfd enable
  The capability of dynamically creating BFD sessions is enabled on the TE tunnel.
  
  After this command is run in the MPLS view, dynamic BFD for TE LSP is enabled on all tunnel interfaces, excluding the interfaces on which dynamic BFD for TE LSP is blocked.
4. (Optional) Block the capability of dynamically creating BFD sessions for TE LSP on the tunnel interfaces of the TE tunnels that do not need dynamic BFD for TE LSP.
  - Run interface tunnel interface-number
    The TE tunnel interface view is displayed.
  - Run mpls te bfd block
    The capability of dynamically creating BFD sessions on the tunnel interface is blocked.
5. Run commit
  The configuration is committed.
Enable MPLS TE BFD on a tunnel interface of the ingress.
1. Run system-view
  The system view is displayed.
2. Run interface tunnel interface-number
  The TE tunnel interface view is displayed.
3. Run mpls te bfd enable
  The capability of dynamically creating BFD sessions is enabled on the TE tunnel.
  
  The command configured in the tunnel interface view takes effect only on the current tunnel interface.
4. Run commit
  The configuration is committed.
