Configure Bit-Error-triggered Protection Switching for a TE Tunnel
Scenario
As shown in the following figure, TE hot standby is deployed on an ASG and RSG in the IP RAN scenario.
Configuration Requirements
The mpls te bit-error-detection command must be run on the ASG's tunnel interface to configure bit-error-triggered RSVP-TE tunnel switching.
Misconfiguration Risks
Risk description:
If bit-error-triggered protection switching has not been configured and bit errors occur on the transmission device between the ASG and RSG, services on the base station connected to the ASG are interrupted.
Identification method:
Check whether bit-error-triggered protection switching has been configured on the ASG's tunnel interface.
Recovery measures:
Perform configurations according to the configuration requirements.
