4.3. Configuring Redundant Ring Protocol (RRP)
Red Hat supports the configuration of Redundant Ring Protocol (RRP) in clusters subject to the conditions described in the "Redundant Ring Protocol (RRP)" section of Support Policies for RHEL High Availability Clusters - Cluster Interconnect Network Interfaces.
When you create a cluster with the
pcs cluster setupcommand, you can configure a cluster with Redundant Ring Protocol by specifying both interfaces for each node. When using the default udpu transport, when you specify the cluster nodes you specify the ring 0 address followed by a ',', then the ring 1 address.
For example, the following command configures a cluster named
my_rrp_clusterMwith two nodes, node A and node B. Node A has two interfaces,
nodeA-1. Node B has two interfaces,
nodeB-1. To configure these nodes as a cluster using RRP, execute the following command.
pcs cluster setup --name my_rrp_cluster nodeA-0,nodeA-1 nodeB-0,nodeB-1
For information on configuring RRP in a cluster that uses
udptransport, see the help screen for the
pcs cluster setupcommand.
