III. Configuring secondary link disconnection delay
You may configure a delay for dynamic routing standby to disconnect the secondary
link after the primary link goes UP.
Perform the following configurations in dial interface view.

Restore the default secondary link
disconnection delay value
The secondary link disconnection delay defaults to 0, meaning disconnecting the
secondary link immediately.

2.3 Dynamic Routing Standby Configuration Example

2.3.1 Dynamic Routing Standby Configuration Example I

I. Network requirements
RouterB is connected to RouterA and RouterC each through a serial interface
encapsulated with X.25.
RouterA and RouterC are connected to an ISDN switched network through ISDN BRI
interfaces, and they can call each other.
The serial interfaces use addresses on the network segment 10.0.0.0 and the BRI
interfaces use addresses on 20.0.0.0.
In dynamic routing standby, RouterA is working as the control device to monitor routes
destined to the segment 30.0.0.0 on Router C.
