BGP Enterprise VS BGP Service Provider

[Ciscomania]

Ho Folks,

Can you tell me which topics should I study,if I am going to support large Enterprise Customers.
So which BGP topics are exactly related for Enterprise?
I know that BGP is using for ISP redundancy...(Multihomed BGP)
What else? 
What about 

• BGP Peer Group
• BGP Route Reflector
• BGP Confederations
• BGP Synchronization
• BGP Backdoor Routes
• MP-BGP (multi-protocol BGP)
• BGP Private and Public AS Numbers
• BGP Remove Private AS Numbers
• BGP Soft Reconfiguration
• BGP Route Refresh Capability
• BGP Allow AS in
• BGP AS Override
  
• BGP Community

Which topics I will face only in Enterprise or only in Service Provider , or both of them

Thank you.

"Large enterprises" are often service providers to their own business units, and as such use all the same technologies as "service providers".

Thank you Philip.

Ok What about medium business Enterprise?
Which BGP technologies I will never use and which I will definitely use?  

[Philip D'Ath · Accepted solution]

I have never used these BGP features in normal "Corporates":

• BGP Backdoor Routes
• MP-BGP (multi-protocol BGP
• BGP Remove Private AS Numbers

Others people's personal experience will vary.
