R0106-HP MSR Router Series MPLS Command Reference(V7)

110
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
Related commands
mpls te backup-path
mpls te backup bandwidth
Use mpls te backup bandwidth to configure the bandwidth and the CT that the bypass tunnel can protect.
Use undo mpls te backup bandwidth to restore the default.
Syntax
mpls te backup bandwidth [ ct0 | ct1 | ct2 | ct3 ] { bandwidth | un-limited }
undo mpls te backup bandwidth
Default
The bandwidth and the CT that the bypass tunnel can protect are not specified.

Parameters
bandwidth: Specifies the total bandwidth that the bypass tunnel can protect, in the range of 1 to
4294967295, in kbps.
ct0: Specifies the bypass tunnel to protect only CRLSPs of CT 0.
ct1: Specifies the bypass tunnel to protect only CRLSPs of CT 1.
ct2: Specifies the bypass tunnel to protect only CRLSPs of CT 2.
ct3: Specifies the bypass tunnel to protect only CRLSPs of CT 3.
un-limited: Puts no limit on total protected bandwidth. This keyword means the bypass tunnel does not
provide bandwidth protection.
Usage guidelines
If you specify the un-limited keyword, the bypass tunnel does not provide bandwidth protection. FRR
does not guarantee the bandwidth of the protected tunnels. If the sum of traffic of the protected tunnels
exceeds the actual bandwidth of the bypass tunnel, traffic of protected tunnels might be lost. The primary
CRLSP that does not need bandwidth protection prefers this type of bypass tunnels over other types of
bypass tunnels.
If you specify the bandwidth argument, the bypass tunnel provides bandwidth protection. The primary
CRLSP that needs bandwidth protection prefers this type of bypass tunnels over other types of bypass
tunnels. If you set the value for the bandwidth argument to 0, the bypass tunnel performs best-effort
