■ With backup enabled, the record route flag is automatically set to record
reroute regardless of whether the mpls te record-route command is
configured.
■ The backup function cannot be used together with these commands: mpls te
reoptimization, mpls te auto-bandwidth adjustment, and mpls te
resv-style ff.
Example # Enable hot backup on tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] mpls te backup hot-standby
mpls te backup bandwidth
Syntax mpls te backup bandwidth { bandwidth | { bc0 | bc1 } { bandwidth | un-limited }}
undo mpls te backup bandwidth
View Tunnel interface view
Parameter bandwidth: Total bandwidth that the bypass tunnel (also called the protection
tunnel) can protect, in the range 1 to 32000000 kbps.
bc0: Indicates that only the LSPs using BC0 bandwidth (global bandwidth) can use
the bypass tunnel.
bc1: Indicates that only the LSPs using BC1 bandwidth (subpool bandwidth) can
use the bypass tunnel.
If neither BC0 nor BC1 is specified, all LSPs can use the bypass tunnel.
un-limited: Puts on limit on total protected bandwidth.
Description Use the
mpls te backup bandwidth command to configure the total
bandwidth and type of LSP that the bypass tunnel can protect.
Use the
undo mpls te backup bandwidth command to remove the
configuration.
By default, bypass tunnels do not protect bandwidth.
If neither BC0 nor BC1 is specified, all LSP can use the bypass tunnel.
