Configuring MRP

Adding an MRP ring to a VLAN
If you plan to use a topology group to add VLANs to the ring, make sure you configure MRP on the
topology group’s master VLAN.
To add an MRP ring to a VLAN, enter commands such as the following.
BigIron RX(config)# vlan 2
BigIron RX(config-vlan-2)# metro-ring 1
BigIron RX(config-vlan-2-mrp-1)# name CustomerA
BigIron RX(config-vlan-2-mrp-1)# master
BigIron RX(config-vlan-2-mrp-1)# ring-interface ethernet 1/1 ethernet 1/2
BigIron RX(config-vlan-2-mrp-1)# enable
These commands configure an MRP ring on VLAN 2. The ring ID is 1, the ring name is CustomerA,
and this node (this device) is the master for the ring. The ring interfaces are 1/1 and 1/2. Interface
1/1 is the primary interface and 1/2 is the secondary interface. The primary interface will initiate
RHPs by default. The ring takes effect in VLAN 2.
Syntax: [no]metro-ring <ring-id>
The <ring-id> parameter specifies the ring ID 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 be 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] master
Configures this node as the master node for the ring. Enter this command only on one node in the
ring. The node is a member (non-master) node by default.
Syntax: [no] ring-interface ethernet <primary-if> ethernet <secondary-if>
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.
You can use two Ethernet interfaces.
To take advantage of every interface in a Metro network, you can configure another MRP ring and
either configure a different Master node for the ring or reverse the configuration of the primary and
secondary interfaces on the Master node. Configuring multiple rings enables you to use all the ports
in the ring. The same port can forward traffic one ring while blocking traffic for another ring.
Syntax: [no] enable
The enable command enables the ring.
