One area that students can struggle with when preparing for the R&S exam is BGP. This happens because students can quickly become overwhelmed by the massive about of features and potential study topics that exist for this important technology.
This blog post serves to remind students of the major aspects they should focus on for the R&S track. It also breaks down the list of study objectives in a suggested attack approach. Notice I like to separate the BGP material into a core and non-core concept. Using my definition of core and non-core for the exam, technically all of your BGP can be non-core in the exam, but notice WITHIN the topic of BGP, we can once again distinguish between core points and non-core. If you do not build the BGP infrastructure correctly, you cannot achieve the other “non-core” BGP points that may follow.
Core BGP
- IBGP Peerings
- EBGP Peerings
- Loopback Peerings
- Next Hop Self
- Route Reflection
- Confederation
- Route Advertising
- Route Redistribution
- Peer Groups
Non-Core BGP – Route Filtering
- ACLS
- Prefix Lists
- AS Path Filters
- Communities
Non-Core BGP – Aggregation
- Summary Only
- Suppress and Unsuppress maps
Non-Core BGP – Best Path
- Weight
- Local Pref
- MED
Non-Core BGP – Misc
- Local-AS
- Private AS
- Route Dampening
- Conditional Advertisement
Notice how far less intimidating things become when we break them down and consider our study plan of attack. I recall getting so fatigued with a massive topic like BGP that I would leave after studying a major section, and then go study something else, only to return to BGP after mastery of unrelated (more fun) topics. If you love the study of BGP, then you will most likely never want to leave! :)
