(Optional) Configuring Forcible Switchover

(Optional) Configuring Forcible Switchover

Context

If a backup CR-LSP has been established and a primary CR-LSP needs to be adjusted, configure the forcible switchover function to switch traffic from the primary CR-LSP to the backup CR-LSP. After adjusting the primary CR-LSP, switch traffic back to the primary CR-LSP. This process prevents traffic loss during the primary CR-LSP adjustment.

Perform the following configurations on the ingress node of an MPLS TE tunnel.

Procedure

  • Before adjusting a primary CR-LSP, perform the following configurations.
    1. Run system-view

      The system view is displayed.

    2. Run interface tunnel tunnel-number

      The MPLS TE tunnel interface view is displayed.

    3. Run hotstandby-switch force

      Traffic is switched to a backup CR-LSP.

      To prevent traffic loss, check that a backup CR-LSP has been established before running the hotstandby-switch force command.

  • After adjusting the primary CR-LSP, perform the following configurations.
    1. Run system-view

      The system view is displayed.

    2. Run interface tunnel tunnel-number

      The MPLS TE tunnel interface view is displayed.

    3. Run hotstandby-switch clear

      Traffic is switched backup to the primary CR-LSP.
