Hi,
Just looking at your diagram. I think you can use two solutions, the following:
- Use tracking, see more details in link below:
http://h22208.www2.hpe.com/eginfolib/networking/docs/routers/msrv7/cg/5200-3011_hi-avail_cg/content/index.htm
- Play with route preferences
But in this case your complete route must be gone. Tracking is much more dynamic
In your diagram I can't see if you are using VRRP down or maybe you want to IRF your routers (that would be even easier I think). Since you need to make sure the clients will also follow the right path.
Hope this will help you!
