MRP Topology overview
The Metro Ring Protocol (MRP) is a IronWare proprietary protocol used to prevent Layer 2 loops and
to provide fast reconvergence in a Layer 2 ring topology. The MRP Topology view displays a map of
the MRP rings on your network. To display the topology map for MRP, you must have the IP - Main
Display – MRP privilege in your user role and the MRP device must be in your area of responsibility
(AOR).
Before you display the MRP topology, make sure you meet the following requirements on your
devices:
• The device is MRP-enabled.
• The devices are running FDP or LLDP.
If you do not enable FDP or LLDP on a product, the product displays without any links.
• The snMetroRingTable MIB table (OID.1.3.6.1.4.1.1991.1.1.3.29.2.1) is enabled on the device
and has MRP configured. This MIB is not supported on third-party products.
MRP Topology view is available for the following devices:
- FastIron Edge Switch running FES software release 04.0.00 and later.
- FastIron X Series devices running FSX software release 04.0.00 and later.
- FastIron CX switches running FCX software release 04.0.00 and later.
- FastIron GS, FastIron LS, and FastIron WS running FGS software release 04.0.00 and later.
