tablished automatically by a packet intended for a destination
outside the LAN. In the latter case, packets can only be sent to a
destination for which the route is known, i.e. for those to which a
logical ISDN connection exists.
l for IPX:
dynamic routing with IPX RIP and SAP on the LAN side and over
ISDN. When a logical connection over ISDN is established for the
first time, RIP/SAP is exchanged and the possible routes in the
network are announced. RIP/SAP is used as long as a logical ISDN
connection exists. NT/MPRI reduces costs by only sending
RIP/SAP updates when changes are implemented.
A static route over ISDN to a Netware server can also be defined.
This had the advantage that the external server is always known
in the local network, even if no logical ISDN connection exists. If
data packets are awaiting transmission to the remote router, the
physical ISDN connection will be established automatically.
Records and Log Functions
Comprehensive records and log functions allow the exact assessment
of all actions on the router:
l status information at
– the NT/MPRI and the ISDN and ADSL-Controller
– the available IP and IPX routes and SAP services as well as the
ARP table
– the physically active ISDN connections
l data about the cost and use for connections as a daily overview or
selected according to specific criteria such as certain destinations
l recording events as a daily overview or selected according to spe-
cific criteria like the “Information” message type
l packet recording with PPP decoding
