Disables the Bidirectional Forwarding Detection (BFD) client for MPLS on the specified VLAN or on all VLANs.
| vlan_name | Specifies the VLAN on which to disable the MPLS BFD client. |
| delete-sessions | Specifies to delete all MPLS BFD sessions. |
Keep existing MPLS BFD sessions.
This command instructs MPLS to cease the establishment of new BFD sessions with neighbors as LSPs are established with those neighbors. The default behavior retains the existing BFD sessions and ignores status updates from those existing sessions. The delete-sessions option instructs MPLS to request the deletion of existing sessions. Whether the sessions are deleted or not, the link state presented to the upper MPLS layers reverts to the normal link operational status.
Note
Deleting existing sessions can result in a neighbor DOWN indication from BFD to MPLS on the other end of the session (the peer switch) and a subsequent interface DOWN indication presented to the upper layers of MPLS on that peer switch. These actions can cause MPLS to reroute or fail the affected LSPs.The following command disables the MPLS BFD client on VLAN vlan1:
disable 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 Feature License Requirements document.
