Inter VLAN Routing
Summary
A router needs to do the following:
识别目标地址;
识别数据来源;
识别去往目标网络可能的所有路由(路径);
选择前往目标网络的最佳路由;
维护路由信息。
Router Operations
路由选择----是确定将本地网络外部的数据分组发送到外部的过程.
Router Operations (Cont.)
路由----用于前往不与目标网络直接相连的网络
Identifying Static and Dynamic Routes
Static Routes
Configure unidirectional static routes to and from a work to munications to occur.
Defines a path to an IP work or or host
Address = IP address of the next hop router
Interface = outbound interface of the local router
RouterX(config)# ip work [mask] {address | interface}[distance] [permanent]
Static Route Configuration
Static Route Example
This is a unidirectional route. You must have a route configured in the opposite direction.
RouterA(config)# ip route
RouterA(config)# ip route s0/0/0
or
Default Routes
This route allows the work to reach all works beyond Router A.
