Configuring MRP with shared interfaces
MRP Phase 2 allows you to enter commands such as the following when configuring MRP.
Brocade(config)# vlan 2
Brocade(config-vlan-2)# metro-ring 1
Brocade(config-vlan-2-mrp-1)# name CustomerA
Brocade(config-vlan-2-mrp-1)# ring-interface ethernet 1/1 ethernet 1/2
Brocade(config-vlan-2-mrp-1)# enable
Brocade(config-vlan-2-mrp-1)# metro-ring 2
Brocade(config-vlan-2-mrp-2)# name CustomerB
Brocade(config-vlan-2-mrp-2)# ring-interface ethernet 1/1 ethernet 1/2
Brocade(config-vlan-2-mrp-1)# enable
Syntax: [no] metro-ring ring-id
The ring-id parameter specifies the ring ID, which can be from 1 – 255. Configure the same ring ID
on each of the nodes in the ring.
Syntax: [no] name string
The string parameter specifies a name for the ring. The name is optional, but it can have up to 20
characters long and can include blank spaces. If you use a name that has blank spaces, enclose
the name in double quotation marks (for example: “Customer A”).
Syntax: [no] ring-interface ethernet
The ethernet primary-if parameter specifies the primary interface. On the master node, the primary
interface is the one that originates RHPs. Ring control traffic and layer 2 data traffic will flow in the
outward direction from this interface by default. On member nodes, the direction of traffic flow
depends on the traffic direction selected by the master node. Therefore, on a member node, the
order in which you enter the interfaces does not matter.
The ethernet secondary-if parameter specifies the secondary interface.
Syntax: [no] enable
The enable command enables the ring.
Tuning MRP timers
To effectively tune MRP timers it is crucial to understand the association between the hello time
and the preforwarding time.
Flushing the mac table following an MRP event
After an MRP event switches in the ring flush MAC tables and relearn to ensure correct forwarding
paths. Notification to flush is carried out by sending topology change RHP’s.
