巧用交换机Trunk功能实现网络中继

在信息网络系统建设过程中，如果网络汇聚节点与核心节点受到距离与通道资源等客观条件限制，往往只能采用租用或自建的低带宽通道互联，这样势必会带来网络性能低、稳定性差等实际问题。为解决这一问题，选取合适的信息网络中继节点，利用交换机的Trunk功能进行VLAN透传中继，是一种经济可行的方法。

Using the Trunk function of switch to realize the network relay

In the process of the construction of Information Network System, if the network convergence nodes and the core nodes is limited by distance, channel resources and other objective conditions, can only use the low bandwidth channel which rented or self to connect Internet, this would bring the network performance is low, poor stabilityo In order to solve this problem, select the appropriate network relay node, using the Trunk function of switch and the VLAN transparent to realize the network relay is a feasible method for economic.
