Re: Bring physical interface down (with object tracking)
1- change the timers to a lower value.
When changing the timers to lower value it will take too long to realize that the neighbor cant be reached through the physical interface, since the interface is in up/up or up/down state.
2- use BGP next-hop tracking feature.
This case is the same as the one described above.
I do remember a solution where you can bring a physical interface down with unnumbered IP on it, but it was for serial interface (in my case its ethernet). I remember Brian Dennis from internetwork experts describing a way to do it, but I lost that CBT now.
