Configuration Procedure; Configuring Cr-Lsp Backup - HP HSR6800 Configuration Manual

this timer, MPLS TE resizes the tunnel bandwidth using the maximum tunnel output rate
sampled before the expiration of the timer as the bandwidth constraint to set up a new LSP
tunnel. If the setup attempt succeeds, traffic is switched to the new LSP tunnel and the old LSP
tunnel is cleared. If the setup attempt fails, traffic travels the existing LSP tunnel.
•
When resetting the automatic bandwidth adjustment function, the system clears information
about output rate sampling and the remaining time for next bandwidth optimization.

Configuration procedure

To configure automatic bandwidth adjustment:
Step
1. Enter system view.
2. Enter MPLS view.
3. Enable automatic bandwidth
adjustment, and configure
output rate sampling for
automatically bandwidth
tuned TE tunnels.
4. Configure the interval for
advertising bandwidth.
5. Return to system view.
6. Enter MPLS TE tunnel
interface view.
7. Configure automatic
bandwidth adjustment for the
TE tunnel.
8. Configure the interval for
polling the output rate of the
TE tunnel.
9. Submit current tunnel
configuration.
10. Return to user view.
11. Reset automatic 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.
