Each row in the AppleTalk routing table corresponds to an AppleTalk
route or network range. If the list of routes shown exceeds the size
of the screen, you can scroll through it by using the SCROLL UP and
SCROLL DOWN items.
To scroll up, select the SCROLL UP item at the top of the table and
press the Return key. To scroll down, select the SCROLL DOWN
item at the bottom of the table and press the Return key.
The table has the following columns:
Net: Displays the starting network number supplied by the AppleTalk
router in the 'Next Rtr Addr. Column'. If a network number is
preceded by an asterisk (*), it has multiple zones. To display the
zones, select the network entry and press Return.
Range: Displays the ending network number for the extended
network.
(Def) Zone Name: Displays the zone or zones associated with the
specified network or network range. The zone name shown is either
the only zone for a non extended network (e.g.:LocalTalk networks),
or the default zone name for an extended network. To see the
complete list of zones for an extended network with multiple zones,
select the entry in the table and press the Return key. Press the
Return key again to close the list of zones.
Hops: Displays the number of routers between the Netopia ISDN
Router and the specified network.
State: Displays the state of the specified route, based on the
frequency of Routing Table Maintenance Protocol (RTMP) packets
received for the route. The state can be Good, Suspect, or Bad.
AppleTalk routers regularly exchance RTMP packets to update
AppleTalk routing information.
Next Rtr Addr.: Displays the DDP or IP address of the next hop for
the specified route. A DDP address is displayed if the router shown
is on the local AppleTalk network. DDP address means that a
connection to the next hop router is by a native AppleTalk network
(e.g.: LocalTalk or EtherTalk Phase II). An IP address is displayed if
the Netopia ISDN Router is connected to the router shown using
AURP. IP address means a connection transports over AURP
(AppleTalk encapsulated IP).
