AppleTalk Routing E-3
TokenRing and Ethernet are considered “extended networks” while
LocalTalk is considered a “non-extended network”. Extended networks
may have a range of one or more network numbers. Associated with this
range may be one or more zone names. Non-extended networks may have
only a single network number, and one zone name.
Here are some sample ranges and zones for various interfaces.
Note that it is legal and possible to have the same zone name associated with
multiple network ranges. the relationship between network numbers and
zone names is very flexible.
Learning and Forgetting Routes
The NetBlazer uses AppleTalk learning and forgetting of routes to make
building and updating of routing tables a little easier. Instead of manually
entering all the information about a route on a remote LAN, Learning adds
the routing information to your AppleTalk routing table for you.
When you tell your NetBlazer to learn routes on a remote LAN connection,
the NetBlazer “listens” on the line to information distributed by AppleTalk
Seed Routers and adds that information to its routing tables.
When the remote network’s topology changes, you can tell the NetBlazer to
forget all of the routes learned on for that remote LAN connection.
Removing the learned entries removes any bad routes in your routing table.
You then tell the NetBlazer to learn the routes on that connection again, to
update the routing table with the most recent (and most correct) information.
