RI on the ML-Series card has these characteristics:

Supported only on Gigabit Ethernet

Provisioned by identifying peer RPR MACs as either primary or standby

Uses an OAM frame to flush the spatially aware sublayer (SAS) table and MAC table at the add
stations

Provides protection between individual RPRs, including:

Two RPRs

Two Cisco proprietary RPRs

A Cisco proprietary ring and an IEEE 802.17 ring

Provides card-level redundancy when connected to a switch running EtherChannel
