ROUTING IN VIRTUAL PRIVATE NETWORK |
摘要 |
A router providing selective routing depending on traffic direction. The router includes two IP interfaces, where each IP interface is associated with a respective virtual private network. The router uses two forwarding tables. The first forwarding table routes traffic towards a first IP interface and a second forwarding table is capable of simultaneously routing traffic in the opposite direction, away from the first IP interface. The first IP interface is coupled to a first tunnel which provides bi-directional connectivity to mobile stations. The second IP interface is coupled to a second tunnel providing bi-directional connectivity to a corporate network. The router also includes a third interface which provides bi-directional connectivity to mobile stations. The router routes traffic through the second interface in the event that a mobile station on one interface is communicating with a mobile station on the third interface. |
