mpls te backup
Use mpls te backup to enable CRLSP backup and specify the backup mode for a tunnel.
Use undo mpls te backup to restore the default.
Syntax
mpls te backup { hot-standby | ordinary }
undo mpls te backup
Default
Tunnel backup is disabled.
Views
Tunnel interface view
Predefined user roles
network-admin
Parameters
hot-standby: Enables hot backup for the tunnel. In this mode, a backup CRLSP is established immediately
after the primary CRLSP is established. When the primary CRLSP fails, MPLS TE immediately switches
traffic to the backup CRLSP.
ordinary: Enables ordinary backup for the tunnel. In this mode, a backup CRLSP is established after the
primary CRLSP fails.
Usage guidelines
When backup is enabled for a tunnel, the record route flag is automatically set for the tunnel, regardless
of whether the mpls te record-route command is configured.
In the same tunnel interface view, the mpls te backup command cannot be used together with the mpls
te reoptimization, mpls te auto-bandwidth adjustment, and mpls te resv-style ff commands.
Examples
# Enable hot backup for tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
[Sysname-Tunnel0] mpls te backup hot-standby
