Usage Scenario
If a hot-standby CR-LSP is established and a primary CR-LSP needs to be adjusted, run the hotstandby-switch force command to switch traffic forcibly to the hot-standby CR-LSP. After the primary CR-LSP has been adjusted, run the hotstandby-switch clear command to disable the forcible switchover function and switch traffic back to the primary CR-LSP.
Prerequisites
A hot-standby LSP has been created. The display mpls te tunnel-interface command output shows that the hot-standby LSP has been established.
Precautions
When using the hotstandby-switch force command, note the following points:
- Before running the hotstandby-switch force command to switch traffic to a hot-standby LSP, ensure that a backup CR-LSP has been established. Otherwise, packet loss occurs. You do not need to run the commit command to commit the hotstandby-switch force command configuration.
- If you configure the non-revertive operation mode for a hot-standby CR-LSP, the hotstandby-switch clear command configuration does not take effect.
- If you configure the revertive operation mode for a hot-standby CR-LSP and the revertive switching delay is not 0, running the hotstandby-switch clear command causes an intermediate CR-LSP switchover.
