Description
Configure the IP address to be used when the Routing Engine is the current primary.
When you use the master-only cli command, you cannot use the
management interface (fxp/em0) IP as the source address for services like system
logging. If you use the management interface, the error eventd: could
not bind to address x.x.x.x: Can't assign requested address is
displayed from backup routing engine. This error occurs because the backup
routing engine does not have access to master-only IP.
