XCON: Consequences of an Unavailable Routing Group Master Server (261827)

MORE INFORMATION

When a server in a routing group determines that the state of a connector assigned to it has changed (gone up or down), it attempts to update link state information on the master server with the new information. If the master server is unavailable, it cannot update this information. The result is that servers in the organization continue to operate with old (possibly incorrect) information about the connectors in the routing group whose master is unavailable. Information about connectors in other routing groups continues to be updated when the connectors go up or down, and servers in the routing group with the unavailable master server continue to receive information about the state of other routing groups as mail is transferred.

The network operates less efficiently when the master server is down, and every reasonable effort should be made to make the master server available to all servers in the routing group at all times.

NOTE: Even if the routing group master server is down, all servers continue to operate with loop-free link state data.
