Optional.
After this command is executed,
the system clears the output rate
sampling information and the
remaining time to the next
bandwidth adjustment to start a
new output rate sampling and
bandwidth adjustment.
Configuring CR-LSP backup
CR-LSP backup provides end-to-end path protection to protect the entire LSP.
Before you configure CR-LSP backup, complete the following tasks:
• Configure basic MPLS.
• Configure basic MPLS TE.
• Configure MPLS TE tunnels.
Configure CR-LSP backup mode at the ingress node of a tunnel. The system automatically selects the
primary LSP and backup LSP. You do not need to configure them.
To configure CR-LSP backup:

Command Remarks
1. Enter system view of the
ingress node.

2. Enter MPLS TE tunnel interface
view.

3. Enable the specified backup
mode for the current tunnel.

Disabled by default.
4. Submit current tunnel
configuration.

Configuring FRR
FRR provides quick but temporary per-link or per-node local protection on an LSP.
Bypass tunnels are pre-established and require extra bandwidth. Use bypass tunnels to protect only
crucial interfaces or links.
You can define which type of LSPs can use bypass LSPs, whether a bypass LSP provides bandwidth
protection, and the sum of protected bandwidth.
The bandwidth of a bypass LSP is to protect the protected LSPs. To guarantee that a protected LSP can
always bind with the bypass LSP successfully, make sure the bandwidth assigned to the bypass LSP is not
less than the total bandwidth needed by all protected LSPs.
