Example: Configuring Load Balancing Within Ethernet Ring Protection for MX Series

Routers

MX Series routers support Ethernet ring protection (ERP) to help achieve high reliability

and network stability. ERP is used in router or bridge networks to protect against link

failure. A single-ring topology is configured that uses one specific link called a ring

protection link (RPL) to protect the whole ring. When all links are up and running, the

RPL blocks traffic and remains idle. However, if a link fails, the RPL routes traffic to bypass

the failure on the ring.

MX Series routers now support ERP ring instances. Whereas traffic in a ring topology

follows the same path, traffic within a ring instance uses data channels to allow some
