How the Bay Networks AppleTalk Router Works
This section describes the following AppleTalk protocols and notes any Bay
Networks divergences from these standards:
• TokenTalk Link Access Protocol (TLAP)
• EtherTalk Link Access Protocol (ELAP)
• AppleTalk Address Resolution Protocol (AARP)
• Datagram Delivery Protocol (DDP)
• Routing Table Maintenance Protocol (RTMP)
• Zone Information Protocol (ZIP)
• Name Binding Protocol (NBP)
• AppleTalk Echo Protocol (AEP)
• AppleTalk Update-based Routing Protocol (AURP)
This section also describes how a Bay Networks AppleTalk interface initializes on
the network.
AppleTalk Link Access Protocols (TLAP and ELAP)
The Bay Networks AppleTalk router uses AppleTalk Link Access protocols to
transmit packets between nodes on the
same
physical network. (TokenTalk
controls data transmission on Token Ring networks; EtherTalk controls data
transmission on Ethernet networks.) The router also supports Fiber Distributed
Data Interface (FDDI) and Bay Networks-proprietary synchronous encapsulation.
Note:
The Bay Networks AppleTalk router does not support LocalTalk or
AppleTalk Phase 1 routing and therefore cannot directly attach to nonextended
networks.
