ip address 172.20.10.2 255.255.255.0

!--- The remote address is in the same subnet.
encapsulation ppp
ip ospf demand-circuit
!--- This forces OSPF to keep the routing table intact when the DDR link
!--- is down. This should only be configured on one router for a
!--- point-to-point circuit.
dialer idle-timeout 900
!--- Idle timeout is set to 900 seconds (15 minutes).
!--- The link will be disconnected if there is no interesting traffic
!--- for 900 secs.

dialer map ip 172.20.10.1 name maui-nas-05 broadcast 5551112
!--- dialer map statements for the remote router
!--- The name must match the one used by the remote router to identify
!--- itself. The broadcast keyword is required to send broadcast traffic
!--- over the link(for OSPF). The two different phone numbers correspond
!--- to the b-channels of the remote side. The multiple statements allow
!--- the router to dial the second number if the first number is busy.
dialer load-threshold 80 outbound
!--- This set the load level for traffic at which additional connections
!--- will be added to the Multilink PPP bundle.!--- Load level values range from 1 (unloaded) to 255 (fully loaded).
!--- The threshold in this case is 80/255 = 32%.
