5.6 The Static Route Screen
In a subnetted LAN environment the X6004 is typically connected to a router. The
router specifies the subnet to which the X6004 is directly connected and the
X6004 has no knowledge of the subnets beyond. For instance, the X6004 knows
about the IP phones in subnet N1 in the following figure. However, the X6004 is
unable to route a packet to phones in subnet N2 because it doesn't know that
there is a route through Router 1 (R). Static routes tell the X6004 about the
subnets beyond the router to which it is directly connected.
