Local Network Name

Each local network must have a globally unique network name.

One convenient way to generate globally unique network names is to concatenate the UDP service, the network specification, and the DNS domain name. For example, 7500.fooNet.baz.com could refer to a local network using service 7500; in contrast, the name 7522.fooNet.baz.com would refer to the local network using service 7522 on the same physical network.

Although that naming scheme is convenient, it can sometimes adversely affect network bandwidth use. Consider using shorter unique names in these situations:

•

When WAN bandwidth is severely limited.

•

When the average message is very small (smaller than 50 bytes).

Like router names, each local network name is a string of alphanumeric, dot, and dash characters. The maximum total length of the string is 64 characters (including the dot separators).

Warning

When several routing daemons serve one local network, each routing daemon must specify the same name for that network. That is, if two local networks use the same physical network and the same service, then they are really the same local network. It is an error to refer to that local network with two or more different names.
