The mpls l2vpn ignore-te-oam-state command configures PWs to ignore the recursive tunnel status detected by MPLS OAM/MPLS-TP OAM.
The undo mpls l2vpn ignore-te-oam-state command restores the default configuration.
By default, PWs determine their own status based on both the actual recursive tunnel status and the one detected by MPLS OAM/MPLS-TP OAM.
Usage Scenario
When MPLS OAM/MPLS-TP OAM is used to detect recursive tunnel status, PWs determine their own status based on both the actual recursive tunnel status and the one detected by MPLS OAM/MPLS-TP OAM. A PW is Down so long as one of the two statuses is Down. In real-world situations, a tunnel may be normal even if the tunnel status detected by MPLS OAM/MPLS-TP OAM is Down. For example, when MPLS OAM/MPLS-TP OAM is enabled or disabled, the tunnel status detected by MPLS OAM/MPLS-TP OAM is momentarily Down due to the time difference of configurations on both ends. If the PW goes Down because the recursive tunnel status detected by MPLS OAM/MPLS-TP OAM is Down, PW traffic will be momentarily interrupted. To prevent this problem, run the mpls l2vpn ignore-te-oam-state command to configure PWs to ignore the recursive tunnel status detected by MPLS OAM/MPLS-TP OAM.
Prerequisites
MPLS L2VPN has been enabled using the mpls l2vpn command.
Configuration Impact
After the undo mpls l2vpn ignore-te-oam-state command is run, PWs cannot recurse to tunnels with OAM faults.
