Is it possible to associate object tracking IP SLA with BGP conditional advertisement?
If I only use the BGP conditional advertisement then I will still need to wait for the route timeout but the user application can't wait that long so I am wondering if anyway to associate the object tracking with conditional advertisement.
Or if there is any work around to withdraw the BGP route when remote route not reachable immediately?
The problem I've seen with MPLS and CSC is broken labels in the path.
The BGP session (PE<->PE) will remain up and the routes will be in the table but there is a blackhole. Nasty scenario.
What I've seen done to workaround this dilemma is to advertise loopbacks from the CE to the MPLS Backbone via BGP and create another BGP peer CE<->CE with those loopbacks. As soon as the loopbacks aren't reachable, the BGP session will go down.
