Wrapping the Packets
If a line breaks, the ring is reconfigured using ringlet 0 and 1 together. RPR "wrapping" causes the two nodes at either side of the break to become return nodes and provides the fastest recovery.

Steering the Packets
RPR "steering" can restore a damaged network and also shorten the number of hops packets take compared to wrapping. However, steering takes a little bit longer to complete as all nodes in the network have to be reconfigured. Sometimes, wrapping is performed immediately, and steering is performed afterwards.
