Handling MPLS task on the Lab
Wanted to get your feedback on how one should be handling MPLS tasks and "full connectivity" requirements.
What I find is that the labs are layed out in a particular order, ie.-Switching then Routing, then BGP/MPLS, then services. This makes sense as this is how on should build this.
When we get get to the MPLS section in our labs, when configuring PE to PE connectivity, we may lose connectivity to those subnets which form the MPLS core. Now, to me, this makes sense as in the real world we do not see any routes/information that creates the SP's MPLS backbone. We only see the routes from our other sites; anything that is imported and is redistributed between BGP and our IGP.
On the exam, how are we to handle this? Are we to assume full reachability/connectivity, even though there is the posibility of lose of reachability due to the technolgies being implemented? Or are we to accept the lose of those subnets, at the sacrafice of meeting the requirement? Or are the labs meant to take this into account and would not put a student in this awkward scenario?
Or am I just overthinking and worrying too much [*-)]
