In the lab there will usually be multiple ways to do things. I have a
couple of examples in mind which illustrate which tactics to apply:
1 BGP neighbours - for iBGP especially, in practice, I would
normally build a link between loopbacks, use update-source etc.
Assuming there is nothing in the question which states one way or the
other what should be done, do you good people have a view for whether
you would prefer loopbacks and update-source over just using the
addresses on the physical links?
2 redistribution between routing domains - it may be possible to
just use one point of redistribution and avoid the fun and games of
route tagging etc. On the other hand, there may be more than two
points where redistribution could be done, which would, arguably, make
the network more resilient once the tagging or distribute-lists are
sorted out. Would you folk consider that there would be a principle
of doing the CCIE lab to prefer reliability over simplicity?
Simplicity or reslience .. is either preferred where no guidance is
given to the contrary, or is this just an 'ask the proctor' job ? I
imagine asking the proctor would be good, and I think the answer from
them will be to 'do as you choose within the bounds of the question',
but I'd like to know what the group's general attitude is.
cheers
Danny
