Hi Samarh; It makes sense now, I have a couple of friends studying for R&S and they kinda told me how to configure it but didnt quite catch the idea. It makes sense now.
I dont recall if the backup route had a lower AD (for SLA minitor) but in any case Based on ur explanation the Null route has to have lower AD than both static configured routes is that correct? Also, is the DSG for this already released? (Just asking, i kinda like not having it right now to see how bad I am doing :)) Thanks Sent from my iPhone On Apr 12, 2013, at 8:01 PM, "Samarth Chidanand" <[email protected]> wrote: > Hi Mike: > > This is a bit tricky question.
