Hi again
the link selection is useful only when peers is manage locally,
in my scenario its 3rd party , i follow all the articles and its looks that vti is the best choice for that,
so there is any detailed guide for the following scenario:
1. ISP use only 1 public ip
2. we use 2 available public ip with primary/backup tunnel
3. when we create tunnel interface on our side we create only 1 vti ?
4. in the 3rd party side need to create 2 vti ? one for each our public ip ?
5. our default route 0.0.0.0 is from BGP from both ISP peers
