R3303-HP HSR6800 Routers MPLS Command Reference

143
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 Tunnel0.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] mpls te backup hot-standby
mpls te backup bandwidth
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.
Views
Tunnel interface view
Default command level
2: System level
Parameters
bandwidth: Total bandwidth that the bypass tunnel can protect, in the range of 1 to 32000000 kbps.
ct0: Specifies that only the LSPs of CT 0 can use the bypass tunnel.
ct1: Specifies that only the LSPs of CT 1 can use the bypass tunnel.
ct2: Specifies that only the LSPs of CT 2 can use the bypass tunnel.
ct3: Specifies that only the LSPs of CT 3 can use the bypass tunnel.
un-limited: Puts on limit on total protected bandwidth.
Usage guidelines
This command is not supported when the signaling protocol is CR-LDP.
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 may be overwhelmed after FRR switchover, causing the protected tunnel to be torn
down.
