Target Applications
IP and Serial Protocols over Frame Relay
Introduction
The Vanguard 340 and 340 Enhanced support multi protocol encapsulation of IP
traffic and serial protocols over frame relay as specified by RFC 1490. As shown in
Figure 1-3, a SNA cluster controller connects to a serial port on the Vanguard 340
and the Ethernet LAN connects to the 10/100BaseT Ethernet port. The Vanguard is
fully interoperable with third party routers via RFC 1490.
