Functional Overview of the Vanguard Router Model Functional Overview of the Vanguard Router Model Introduction Vanguard devices provide interconnection of LANs over WAN using a routing model based on X.25 packet switching technology. Traffic from a LAN port passes internally to a WAN port via a virtual circuit call. Most other bridge and router manufacturers configure WAN links based on physical connections only.
IP Forwarder IP Forwarder Introduction The IP Forwarder provides the Routing, Bridge, or Bridge-Routing function in the Vanguard. Note For more information on Bridge-Router functions refer to “Using Bridging Routers to Connect LANs and Networks” section on page 2-31. Virtual Circuits The connection point of the IP forwarder to the LAN port is a virtual circuit called a Defined by Router Router Interface.
The Vanguard WAN Adapter allows Vanguard LAN software to implement a more efficient layer of routing. An overlay network that the LAN routing functions see is superimposed on top of the actual virtual circuit network and physical network implemented by the Motorola access devices. WAN Adaptor Figure 2-2 shows how the WAN Adapter is used to provide a LAN overlay network.
Page 21
WAN Adapter Flow Control Data passed from the LAN protocol stacks to the WAN Adapter may be queued inside the WAN module. This is due to the relatively low bandwidth of the WAN port(s) compared with a LAN port and to competition for that limited WAN port bandwidth with serial data access ports.
WAN Adapter LCON Encapsulation Introduction The WAN Adapter encapsulates protocol-specific information in the data packet that is needed at the remote end of the connection. The following encapsulation methods are used: • Codex Proprietary encapsulation • RFC 1294 Multiprotocol encapsulation •...
Trailer • Byte 1: Indicates the protocol type of the LAN forwarder, such as SR, STPE, and IP. The key Protocol IDs are: IP=00, IPX = 07, Motorola Codex SR=64, Motorola Codex STPE=65, and Motorola Codex TB=66. • Byte 2: Indicates other packet-specific information. This byte contains information that is copied from the Control field portion of the Application field of the packet header.
Note: The RFC1204 encapsulation to a Bypass FR station is used for interoperability with non-Motorola Type=0 routers. Codex Trailer Flags Flag Note: Motorola to Motorola links are recommended to use Codex encapsulation over Annex G-type Frame Relay stations. Figure 2-3. Packet Formats Vanguard Routing Model...
Router Maximum Transmission Unit (MTU) size is derived via WAN packet size negotiation at the X.25 layer. Instead, the Vanguard Router supports a configurable MTU size as specified in RFC1356, described below. Otherwise, the Motorola version complies with all RFC877 requirements. Refer to the IP Interface Configuration Table menu for more information on MTU size.
WAN Adapter RFC1356 Multiprotocol Encapsulation Overview RFC1356 and RFC877 encapsulation standards are virtually the same. The Vanguard Router complies with RFC1356 encapsulation over X.25 with the following exceptions: • While RFC1356 specifies multi-protocol support, only the IP protocol is supported. •...
WAN Adapter LAN Connection Encapsulation Examples Examples The following examples illustrate LAN traffic encapsulation by • Codex Proprietary Encapsulation • Frame Relay - RFC 1294 and RFC 1490 LCON over X.25 Figure 2-4 depicts LAN traffic encapsulated by Codex Proprietary Encapsulation for using Codex transport over an X.25 network.
Page 28

LANView of the WAN - Group LCONs Vanguard Router Figure 2-15 is an example of LANView interoperating with a Cisco backbone. The using LANView key difference in this application is that even though RFC877 is used as the Interoperating with interoperability encapsulation between the routers and other RFC877-compliant Cisco Backbone routers, connectivity between the routers uses the CODEX encapsulation.
IP. As it is best effort service, UDP does not guarantee reliable delivery. The Real Time Protocol (RTP) resides on top of UDP/IP and provides fast delivery of real time traffic such as voice. Motorola’s implementation of VoIP uses UDP/IP or RTP/UDP/IP protocols to carry packetized voice.

Page 46
RTP/UDP/IP Header Compression 4-bit Sequence Number Each packet is numbered sequentially from 0 to 15. The decompressor on the receiving Vanguard uses the sequence number to determine if packets are received out of sequence or if there is packet loss. The decompressor recomputes the UDP checksum of every 16th decompressed packet.
There can be several different values for the Data Link (MAC) destination address used with the packet. The Data Link address may • Addressed to the Motorola internetworking node itself (case 1) • Addressed to some other node (case 2) •...
