設備選用Catalyst5500交換機1臺，安裝WS-X5530-E3治理引擎，多塊WS-X5225R及WS-X5302路由交換模塊,WS-X5302被直接插入交換機，通過二個通道與系統背板上的VLAN 相連，從用戶角度看認為它是1個1接口的模塊，此接口支持ISL。在交換機內劃有3個虛擬網，分別名為default、qbw、rgw，通過WS-X5302實現虛擬網間路由。
以下加重下橫線部分，如set system name5500C為需設置的命令。

設置如下：

Catalyst 5500配置：

3.1. 例二：

交換設備仍選用Catalyst5500交換機1臺，安裝WS-X5530-E3治理引擎，多塊WS-X5225R在交換機內劃有3個虛擬網，分別名為default、qbw、rgw，通過Cisco3640路由器實現虛擬網間路由。交換機設置與例一類似。

路由器Cisco3640，配有一塊NM-1FE-TX模塊，此模塊帶有一個快速以太網接口可以支持ISL。Cisco3640快速以太網接口與交換機上的某一支持ISL的端口實現連接，如交換機第3槽第1個接口（3/1口）。
