Cisco created the frame relay end-to-end keep alive command to address just the issue you describe. It actually sends a configurable keep alive between the end points to verify connectivity.
Check out the Doc CD Wan Switching Guide. Look under frame relay and the entire keepalive command set is there. -----Original Message----- From: Joshua Gottlieb [mailto:[EMAIL PROTECTED]] Sent: Monday, November 26, 2001 4:00 PM To: [EMAIL PROTECTED] Subject: Frame Relay/ISDN Question [7:27386] Question, I have a network that is connected via frame relay. Each site also has BRI Lines setup from ISDN Dial-Backup. The "backup interface BRI1/0" command is on the PVC Sub-Interface on each router. Occasionally, we will have a problem with our PVC and it will still show up, but we won't be able to route traffic over it. I'm trying to figure out a config so that if the traffic times out on the serial interface, it will DDR on the BRI line. The problem is, that with the "Backup Interface" command, the BRI line goes into Administratively down mode, so I don't think a floating static route will work. Any ideas?
