AppleTalk Interfaces 459
Important
Considerations
Before configuring AppleTalk interfaces, review the following guidelines
and considerations:
■
Your system can support up to 32 AppleTalk interfaces.
■
Each seed interface supports up to 16 zones.
■
Your system supports a maximum of 1 AppleTalk interface per VLAN;
overlapping AppleTalk interfaces on a bridge VLAN is not allowed.
■
A seed router interface will maintain its configuration (local zone and
local network information) even if the information conflicts with other
routers on the same network.
■
The network range is a contiguous range of numbers between 1 and
65,279.
■
The network node number that a router dynamically assigns to itself is
a value between 1 and 253, inclusive.
■
Node numbers 0, 254, and 255 are reserved by the AppleTalk
protocol.
■
The maximum number of active AppleTalk devices on a network is
equal to the number of network numbers multiplied by the number of
possible node numbers.
■
All seed routers on a network must have the same value for both the
start and end of the network number range. For example, if you have
a segment to which multiple routers are attached and you have
assigned a network range of 4–9, then all seed router ports attached
to the segment must be configured with a network range of 4–9.
■
All seed routers on a network must be configured with the same zone
names. For example, if you have a segment to which multiple routers
are attached and you have assigned the zone names
Sales and
Marketing to the segment, then all seed routers attached to the
segment must be configured with zone names
Sales
and
Marketing
.
■
A router will not advertise its routing table through an interface until
that interface has an associated network number range.
■
An interface is not added to the routing table until it has an associated
network number range.
Changing the zone association for an existing network number involves
the deletion of the existing zone association for that network from all
routers on the segment. For details, see “Changing Zone Names” later in
this chapter.
