Description

In the case of multi-homed brokers (i.e. that can be addressed by more than one
name/address), the route-map feature of qpid-route can list the same broker
more than once. This is because it indexes its list of brokers by the URL (not
the broker's uuid).

Version-Release number of selected component (if applicable):

1.1.6 / 1.2

How reproducible:

100%

Steps to Reproduce:
1. Start two brokers on your local system (ports 5672 and 10000)
2. Create a bidirectional set of dynamic federation routes:

$ qpid-route dynamic add localhost localhost:10000 amq.topic
$ qpid-route dynamic add localhost:10000 localhost amq.topic

3. View the route map:

$ qpid-route route map

Finding Linked Brokers:
localhost:5672... Ok
localhost:10000... Ok

Dynamic Routes:

Exchange amq.topic:
localhost:10000 <=> localhost:5672

Static Routes:
none found

4. View the map again using the ethernet hostname (i.e. not "localhost")

$ hostname
dhcp-100-18-254.bos.redhat.com
$ qpid-route route map dhcp-100-18-254.bos.redhat.com

Finding Linked Brokers:
dhcp-100-18-254.bos.redhat.com:5672... Ok
localhost:10000... Ok
localhost:5672... Ok

Dynamic Routes:

Exchange amq.topic:
localhost:10000 => dhcp-100-18-254.bos.redhat.com:5672
localhost:5672 <=> localhost:10000

Static Routes:
none found

Actual results:

Note the fact that three brokers are listed in the second map. This is
incorrect because "dhcp-100-18-254.bos.redhat.com:5672" and "localhost:5672"
are different names for the same broker. This causes confusion in the display
of the routes themselves.

Expected results:

The first map is correct.
