R2511-HP MSR Router Series MPLS Command Reference(V5)

289
[Sysname-Tunnel0] mpls te backup hot-standby
mpls te backup bandwidth
NOTE:
This command is not supported when the signaling protocol is CR-LDP.
Use mpls te backup bandwidth to configure the total bandwidth and type of LSP that the bypass tunnel
can protect.
Use undo mpls te backup bandwidth to remove the configuration.
Syntax
mpls te backup bandwidth { bandwidth | { ct0 | ct1 | ct2 | ct3 } { bandwidth | un-limited } }
undo mpls te backup bandwidth
Default
Bypass tunnels do not protect bandwidth.

Default command level
2: System level
Parameters
bandwidth: Specifies the total bandwidth that the bypass tunnel can protect, in the range of 1 to
32000000 kbps.
ct0: Indicates that only the LSPs of CT 0 can use the bypass tunnel.
ct1: Indicates that only the LSPs of CT 1 can use the bypass tunnel.
ct2: Indicates that only the LSPs of CT 2 can use the bypass tunnel.
ct3: Indicates that only the LSPs of CT 3 can use the bypass tunnel.
un-limited: Puts on limit on total protected bandwidth.
Usage guidelines
If no CT is specified, all LSPs can use the bypass tunnel.
The bandwidth value specified with this command is used for only calculating and determining the
bandwidth protection relationship. No bandwidth will be reserved in the bypass tunnel.
The specified bandwidth value must be less than the actual bandwidth of the bypass tunnel. Otherwise,
the bypass tunnel might be overwhelmed after FRR switchover, causing the protected tunnel to be torn
down.
Examples
# Configure tunnel 0 to provide protection for LSPs of CT 0 without constraining the bandwidth to be
protected. Configure tunnel 1 to provide protection for LSPs of CT 1 and protect up to 1000 kbps
bandwidth.
