HI Bob,
Backup Interface is not a replacement for Interesting Traffic.
Backup interface will hold ISDN down until there is a primary link available and once the link dies, backup interface - ISDN BRI comes up. Now, there should be an interesting traffic to kick off the ISDN - that becomes your IPv6 traffic.
Regards,
Manoj

I have not seen the answers to this lab, however you can do this by creating
dialer interfaces on R5. Then one dialer interface will be the backup for a
frame connection, and the other dialer interface can be used for IPv6
connectivity

8.5. Ensure that R5 can trigger an ISDN call to R4 based on any
IPv6 traffic.
I don't think this is possible since the interface has been previously
configured for a backup interface.
Is this correct or is their a way around this?
