Figure 26-8 RPR RI
Characteristics of RI on the ML-Series Card
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
Caution
When connecting to a switch running EtherChannel, you must configure rpr-ieee ri foreign on the
primary and secondary ML-Series cards.
