configure mpls ldp loop-detection

configure mpls ldp loop-detection [{hop-count hop_count_limit} {path-vector path_vector_limit}]


Configures the loop-detection parameters used by LDP.

Syntax Description

hop-count Configures the number of LSRs that the label message can traverse.
hop_count_limit Specifies the hop count limit. The valid configuration range is from 1 to 255.
path-vector Configures the maximum number of LSR IDs that can be propagated in the label message.
path_vector_limit Specifies the path vector limit. The valid configuration range is from 1 to 255.


The default for the hop-count and path-vector limits is 255.

Usage Guidelines

Configuration changes are only applicable to newly created LDP sessions. Disabling and enabling LDP forces all the LDP sessions to be recreated. LDP loop detection must first be enabled for these configuration values to be used.


This command sets the LDP hop count loop detection value to 10. The configured path vector value remains at 255.

configure mpls ldp loop-detection hop-count 10


This command was first available in ExtremeXOS 11.6.

Platform Availability

This command is available only on the platforms that support MPLS (Multiprotocol Label Switching) as described in the ExtremeXOS 22.2 Feature License Requirements document.
