Configuring MRP

Customer A host attached to Switch D on an interface in vlan 30 can reach the customer A host

attached to Switch B on an interface in vlan 30 through the ring at layer 2. The same mechanism is

used to connect customer B hosts on vlan 40.

Customer A and customer B traffic is separated by using different vlans.

You can configure MRP separately on each customer vlan. However, this is impractical if you have

many customers. To simplify configuration when you have a lot of customers (and therefore a lot of

vlans), you can use a topology group.

A topology group enables you to control forwarding in multiple vlans using a single instance of a

layer 2 protocol such as MRP. A topology group contains a master vlan and member vlans. The

master vlan contains all the configuration parameters for the layer 2 protocol (STP, MRP, or VSRP).

The member vlans use the layer 2 configuration of the master vlan.

In Figure 113, vlan 2 is the master vlan and contains the MRP configuration parameters for ring 1.

vlan 30 and vlan 40, the customer vlans, are member vlans in the topology group. Since a topology

group is used, a single instance of MRP provides redundancy and loop prevention for both the

customer vlans.

If you use a topology group:

• The master vlan must contain the ring interfaces.

• The ring interfaces must be tagged as they will be used for multiple vlans.

• The member vlan for a customer must contain the two ring interfaces and the interfaces for

the customer.

Refer to “MRP CLI example” for the configuration commands required to implement the MRP

configuration shown in Figure 113.

Configuring MRP

To configure MRP, perform the following tasks for each discrete ring:

• On the switch identified as the ring master disable the secondary ring interface. This manually

prevents a layer 2 loop from occurring during configuration.

• Configure each switch for MRP one at a time following the planned flow of RHP’s

• On each switch in the path add an MRP ring to a port-based vlan. When you add a ring, the CLI

changes to the configuration level for the ring, where you can do the following:

• On the master node configure the master ring role.

• Specify the two MRP interfaces for the ring

• Option: Specify a name for the ring. Brocade recommends that you have a naming

convention for your MRP rings and consistently apply names for all the rings in the

topology.

• Option: Change the hello time and the preforwarding time. These parameters control how

quickly failover occurs if the master fails to receive RHPs for the ring.

• Enable the ring.

• Re-enable the interface you disabled in step one. MRP will prevent loops when enabled on all

devices in the ring.

When using topology groups the ring configuration must be added to the master-vlan for the group.

For further information refer to Topology Groups chapter.
