Routing link to protection path

Dear friend!

The principle of link protection is to use the standby link to protect the active link. After the protection function is configured for services on the NMS, services are automatically switched to the standby link if the active link is interrupted.

For details about the MSTP network switchover principle, see the video at the following link:

Thank you!

Hello
That depends on the technology , topology and NE capability
For example , If you use SDH
you have 1+1 , 1:1 , SNCP , MSP ring , pp ring and ASON .
