I have a pair of Cat6500 using GLBP to loadshare traffic.
I have configured the preempt delay and the forwarder preempt delay to 600 seconds.
During testing I have seen instances where these timers are not always obeyed and they preempt immediately.
We are using IOS version 12.2(18) SXD7.
Is anyone aware of any bugs relating to the GLBP timers in this version of IOS?
