<p><b><big>IP Version</big></b><br>Specifies version of IP to use for communication. Value can be one of ipv4 or ipv6. Default (if unspecified) is ipv4.<br></p>
<p><b><big>Bind Network Address</big></b><br>This specifies the address which the openaiscorosync executive should bind. This address should always end in zero. If the totem traffic should be routed over 192.168.5.92, set bindnetaddr to 192.168.5.0.<br>This may also be an IPV6 address, in which case IPV6 networking will be used. In this case, the full address must be specified and there is no automatic selection of the network interface within a specific subnet as with IPv4. If IPv6 networking is used, the nodeid field must be specified.<br></p>
<p><b><big>Multicast Address</big></b><br>This is the multicast address used by openaiscorosync executive. The default should work for most networks, but the network administrator should be queried about a multicast address to use. Avoid 224.x.x.x because this is a "config" multicast address.<br>This may also be an IPV6 multicast address, in which case IPV6 networking will be used. If IPv6 networking is used, the nodeid field must be specified.</p>
<p><b><big>Port</big></b><br>This specifies the UDP port number. It is possible to use the same multicast address on a network with the openaiscorosync services configured for different UDP ports.<br></p>
<p><b><big>Member Address</big></b><br>This list specifies all the nodes in the cluster by IP address. This could be configurable when using udpu(Unicast). <br></p>
<p><b><big>Node ID</big></b><br>This configuration option is optional when using IPv4 and required when using IPv6. This is a 32 bit value specifying the node identifier delivered to the cluster membership service. If this is not specified with IPv4, the node id will be determined from the 32 bit IP address the system to which the system is bound with ring identifier of 0. The node identifier value of zero is reserved and should not be used.<br></p>
<p><b><big>rrp_mode</big></b><br>This specifies the mode of redundant ring, which may be none, active, or passive. Active replication offers slightly lower latency from transmit to delivery in faulty network environments but with less performance. Passive replication may nearly double the speed of the totem protocol if the protocol doesn't become cpu bound. The final option is none, in which case only one network interface will be used to operate the totem protocol. If only one interface directive is specified, none is automatically chosen. If multiple interface directives are specified, only active or passive may be chosen.<br></p>
<p><b><big>Cluster Name</big></b><br>This specifies the name of cluster and it's used for automatic generating of multicast address. Default is hacluster. For a geo cluster, each cluster must have a unique name.<br></p>
<p><b><big>Expected votes</big></b><br>Expect vote number for voting quorum. Will be automatically calculated when the nodelist {} section is present in corosync.conf (the list will be generated when using unicast transport) or can be specified in the quorum {} section (Expect votes should use the total node numble of the cluster). If Expected votes presents in unicast transport, the value will override the one automatically calculated. For safety, the Expected votes will be disabled once nodelist not empty, it's good for ignore the inappropriate Expected votes set.<br></p>
<p><b><big>Auto Generate Node ID</big></b><br>Nodeid is required when using IPv6. Auto node ID enabled will generate nodeid automatically.<br></p>
