Enables the Bidirectional Forwarding Detection (BFD) client for MPLS (Multiprotocol Label Switching) on the specified VLAN (Virtual LAN) or all VLANs.
| vlan_name | Specifies the VLAN on which to enable the MPLS BFD client. |
| vlan all | Enables the MPLS BFD client on all VLANs. |
Disabled.
This command causes MPLS to request a BFD session to each next-hop peer reachable through the named interface. BFD sessions are triggered by the establishment of an LSP over the interface. If this command is issued after LSPs are established, then the list of active LSPs is searched for next-hop peers associated with the named interface, and a BFD session is requested for each neighbor which does not already have a session. This command also instructs MPLS to begin to consider BFD neighbor session state updates as part of the effective interface link state reported to the MPLS upper layer protocols.
Note
BFD must be enabled on the interface before sessions can be established. To enable BFD, use the command: [enable | disable] bfd vlan vlan_name .The following command enables the MPLS BFD client on VLAN vlan1:
enable mpls bfd vlan1
This command was first available in ExtremeXOS 12.4.
This command is available only on the platforms that support MPLS as described in the ExtremeXOS 22.4 Feature License Requirements document.
