Ring Initialization - HP ProCurve 9304M Installation And Configuration Manual

Installation and Basic Configuration Guide
Figure 10.2 Metro ring – multiple rings
In this example, two nodes are each configured with two MRP rings. Any node in a ring can be the master for its
ring. A node also can be the master for more than one ring.
NOTE: In the current release, multiple rings cannot share the same link. For example, you cannot configure ring
1 and ring 2 to each have interfaces 1/1 and 1/2.

Ring Initialization

The ring shown in Figure 10.1 on page 10-5 shows the port states in a fully initialized ring without any broken
links. Figure 10.3 shows the initial state of the ring, when MRP is first enabled on the ring's switches. All ring
interfaces on the master node and member nodes begin in the Preforwarding state (PF).
