The Linkset or Application Servers are identified by their name.

+Routes are inserted in a routing table, where they are ordered first based +on prefix mask length (longest prefix first) and then on priority (lowest value first). +As a result, more specific routes (eg. a single Point Code) will match and +be used before more generic ones (eg. a subnet). + .Major Attributes of an Osmocom SS7 Application Server Process [options="header",cols="25%,75%"] |==== @@ -393,8 +398,16 @@ |Point Code|Destination Point Code for this route |Mask|Destination Mask for this route (like an IP netmask) |Linkset/AS Name|Destination Linkset or AS, identified by name +|Priority|Priority of the route in the routing table; lower value means higher priority |====
