It can be a virtual IP, clarified text: `ha-brokers-url`: A URL listing each node in the cluster. For example `amqp:node1.example.com,node2.example.com,node3.example.com`. If you have separate client and broker networks, the addresses in `ha-brokers-url` should be on the broker network. Note this URL must list all nodes in the cluster, you cannot use a [Virtual IP address][ha-virtual-ip] here. `ha-public-url`: URL used by clients to connect to the cluster. This can be one of: - A [virtual IP address][ha-virtual-ip] configured for your client network. - A list of broker addresses on the client network. If you don't have a separate client network then this is the same as the `ha-brokers-url` > On April 9, 2013, 4:06 p.m., Andy Goldstein wrote: > > /branches/0.22/qpid/doc/book/src/cpp-broker/Active-Passive-Cluster.xml, > > line 613 > > <https://reviews.apache.org/r/10376/diff/1/?file=279332#file279332line613> > > > > assuming the client is configured with a list of urls Can be virtual IP Clients can only connect to the primary broker. Backup brokers reject any connection attempt by a client. Clients rejected by a backup broker will automatically fail-over until they connect to the primary. if <literal>ha-public-url</literal> contains multiple addresses, the client will them all in rotation. If it is a virtual IP address the clients will retry on the same address until it is reconnected. - Alan ----------------------------------------------------------- This is an automatically generated e-mail.
