MRP
MRP (IEEE Std. 802.1ak-2007 Multiple Registration Protocol) is a robust, efficient protocol for declaring
attributes to be registered in a database in each port of each bridge (optionally, station) in a bridged network.
MRP replaces GARP (Generic Attribute Registration Protocol (GARP).
Currently, four applications are based on MRP: MVRP, MMRP, MSRP and MIRP.
MVRP (Clause 11): Attribute is a VLAN ID. MVRP replaces GVRP
•
Stations or configured Bridge Ports make (withdraw) declarations if they do (not) need to receive frames
for a given VLAN ID.
•
If a VLAN ID is registered on a Bridge Port by MVRP, the Bridge knows that that frames for that VLAN ID
should be transmitted on that Bridge Port.
MMRP (Clause 10.9): Attribute is a MAC address, often a multicast address. Replaces GMRP.
•
Stations or configured Bridge Ports make (withdraw) declarations if they do (not) need to receive frames
for a given address. If an address is registered on a Bridge Port by MMRP, the Bridge knows that that
frames for that address should be transmitted on that Bridge Port.
Ports
The MRP Overall Port Configuration page lets you configure MRP
overall settings for all switch ports.
Figure 4-8.1: MRP Overall Port Configuration
Parameter descriptions
:
Port
: The port number for which the following configuration applies.
Join Timeout
: Controls the timeout of the Join Timer for all MRP applications on this switch port. Valid values
are 1-20 centiseconds.
Leave Timeout
: Controls the timeout of the Leave Timer for all MRP applications on this switch port. Valid
values are 60-300 centiseconds.
LeaveAll Timeout
: Controls the timeout of the Leave All
Timer for all MRP applications on this switch port.
Valid values are 1000- 5000 centiseconds.
