Building a Compound Frame Relay Switch
介绍:
试验介绍怎么级联多个低密度串口的路由器使之称为一个高密度串口的帧中继交换机.
通过使用反转线(rollover)连接路由器的aux端口,并且在上面配置GRE通道.
设备列表:
- 2 Cisco Routers with DB-60 Serial Interfaces for Frame Relay Cloud
- 5 Cisco Routers as CPE Devices Connected to the Frame Relay Cloud
- 1 Rollover (Console) Cable
- 5 DB-60 DTE/DCE Serial Cables
配置:
2501 和 2520 通过aux相连而成为一个对CPE设备R1-R5来说透明的一个6端口的帧中继交换机
