Configuring Routed On-Demand Calls
Unlike the "standard" on-demand call, which relies on statically
configured routes and services at each end of a point-to-point connec-
tion, a routed on-demand call runs a routing protocol while the link is
active. When the link goes down, the routers and services made
known by the routing protocol become unavailable. NetWare Multi-
Protocol Router for ISDN 3.1 enables you to configure routed on-
demand calls for each WAN call destination.
If no data crossed the link after some period of time, a Data-Link
layer timer triggers the termination of the on-demand call. However,
the routing protocol running over a routed on-demand call resets this
timer each time it transmits a packet. This keeps the link continuously
active. To solve this problem, NetWare MultiProtocol Router for ISDN
3.1 uses a similar timer that operates at the Network layer. This timer
is reset only when data packets - not protocol packets - cross the link.
In this way, the routing updates do not keep the link active when no
data is being transmitted.
