Hello, i am looking for some help around obscure protocol features that are touched on so very lightly or far and few between that i have some trouble retaining their exact use, and sometimes in cases like BGP where there are a few things that are very similar.
OSPF
-timers, my issue is normally around the wording of the question and what/how a specific timer is tweaked when they often look the same when going to configure
-obscure features that may look alike when worded in a question and i always find myself knowing both options but guessing at the correct one.
BGP
-many of the BGP table walking/scan/advertisement and the wording around the question that helps select the correct choice.
-obscure features, as with the OSPF ones above i find myself guessing quite a few times but knowing that many different options do exist.
I know this is somewhat of a vague question but after revisting INE Vol1 workbooks, ATC videos and other various books/resources im just having an issue with these very few things and any help would be appreciated on resources or guidance to help grab on and remember these topics.
