Figure 1-10. Fully Connected Tunnel
In a partially connected tunnel, two or more exterior routers do not have a
connection. In such a tunnel, routers without an explicit connection cannot see
each other’s networks. This lets network administrators control the view and
access that users have to the resources on various protected networks. An exterior
router in a partially connected tunnel advertises only its local internet. It does not
advertise network information learned through a different connection on the
tunnel (F
igure 1-11).
