Usage guidelines
When route pinning is enabled, an established CRLSP does not re-select an optimal path even if the
optimal route has changed.
Use this feature to avoid CRLSPs from changing frequently on an unstable network. This feature ensures
that the established CRLSPs are not reestablished as long as they are available.
In the same tunnel interface view, the mpls te route-pinning command cannot be used together with the
mpls te reoptimization and mpls te auto-bandwidth adjustment commands.
Examples
# Enable route pinning for Tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
[Sysname-Tunnel0] mpls te route-pinning
