Routing Table (CCU and EUM)
The Routing Table is used by the CCU to determine the routing of IP packets. The routes in
the Routing Table are either entered by the system operator as static routes, or automatically
generated by the CCU. The CCU does not support dynamic routing. As a minimum, the
Routing Table contains the following three routes:
Table 50 Basic CCU Routes
In addition to these standard routes, the system operator may add other routes; for example,
routes to support direct CCU-to-CCU communications, without going back to the NAP router.
Each route in the Routing Table has the following entries:
Table Entry Description
Port The number of the port which is to be filtered.
Filter
For each port listed, the CCU or EUM can be set to filter UDP,
TCP, or both UDP and TCP packets.
Default Route
Any packet with a destination which is not listed in the Routing
Table is forwarded to the gateway address defined in the default
route. Normally, this is be the IP address of the NAP router. The
default route is generated automatically by the CCU when you
enter the gateway IP address.
Radio Subnet Route
Any packet with a destination in the radio subnet (EUMs, end-
user PCs) is forwarded to the CCU radio port. This route is
automatically generated by the CCU, using the CCU radio subnet
IP address, entered by the system operator.
Loopback Route
The loopback interface exists (among other reasons) so the CCU
operating system can talk to itself without handing the packet to a
hardware driver. This route keeps unneeded traffic off the
network. This loopback route is automatically generated by the
CCU.
