GLBP - two preempts
From reading texts and documentation online it appeared to me that GLBP had preempt enabled by default.
I was just doing a GLBP lab exercise when I noticed that "Preemption disabled" was displayed in #sh glbp. After some digging around I found that there are two preempts under GLBP, one for the AVG and one for AVFs. AVF preemption can be verified at the bottom of the #sh glbp output.
For AVFs preempt is enabled by default with a delay of 30 seconds. In order to preempt an AVG you need to set it manually.
AVG: #glbp 1 preempt
Change AVF default:
AVF: #no glbp 1 forwarder preempt
#glbp 1 forwarder preempt [delay minimum seconds]
