Configuring AppleTalk Services
2-32 117366-A Rev. A
Note that AURP supports the following AppleTalk commands over the IP
connecting network:
• Open request and response
• Routing Info request, response, and ack
• Zone Information request and response
• Router down notification
• Tickle and Tickle ack (based on configurable timer)
AURP does not support the following AppleTalk commands over the IP
connecting network:
• GetDomainZoneList request and response
• GetZonesNet request and response
In addition, the following features are not available in the Bay Networks
implementation of AURP:
• Loop detection
• Network number remapping
• Configured alternative backup paths
• Network hiding
The following sections provide general guidelines for understanding and using
some of the most important AURP parameters.
Setting the Update Rate
You should carefully consider how often you want to update your AppleTalk
network. A smaller update rate (for example, 10 seconds) causes routers to
converge more quickly on a network, making most changes to the network appear
quickly in the Chooser application. Though a smaller update rate provides users
with quick access to any zones added to a network, it may also prove to be
expensive (for example, in a dial-on-demand configuration, or over Frame Relay).
