ccielabHello, Brian and Group,
Thanks for your help, I have a question about the virtual-link and dialer-watch.
I saw below messages from cisco website.
---------------------------------------------------------------------------------------------------------------
When a watched route is deleted, dialer watch checks for at least one valid route for any of the IP
addresses or networks being watched.
!'
A. If there is no valid route, the primary line is considered down and unusable.
Dialer watch then initiates the call, and the routers connect and exchange routing
information. All traffic for the remote network will now use the backup link.
!'
B. If there is a valid route for at least one of the watched IP networks defined and the route is
pointing to an interface other than the backup interface configured for dialer watch, the
primary link is considered up and dialer watch does not initiate the backup link.
--------------------------------------------------------------------------------------------------------------------------For the point B, if I received the watched route from OSPF virtual-link, but the virtual-link is built base on the backup ISDN link, the watched route is pointing the backup interface in routing table. In this senario, Does the dialer-watch consider the primary link up???
