mpls te hop-limit (SR Tunnel interface view)

Function

The mpls te hop-limit command sets the maximum number of hops on a tunnel.

The undo mpls te hop-limit command restores the default setting for the maximum number of hops.

By default, the maximum number of hops on a backup CR-LSP is 32.

Usage Guidelines

Usage Scenario

The number of hops on a CR-LSP to be established cannot exceed the hop limit configured using the mpls te hop-limit command.

Precautions

If the default value (32) is used in the hop-limit command, both adjacency and node SIDs can be used for local SR-MPLS TE path calculation. If a non-default value (1?31) is used in the hop-limit command, only adjacency SIDs can be used for local SR-MPLS TE path computation.

Example

# Set the hop limit to 10 for primary and backup tunnels and best-effort paths.
