This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

BGP filtering preference is based on inbound or outbound communications for example:

The order of preference for Inbound
*Route-map
*Filter-list
*Prefix-list
*Distribute-list

The order of preference for outbound
*Distribute-list
*Prefix-list
*Filter-list
*Route-map

Another way to remember is to consider the RFP process with Cisco - RFP into Cisco

R - Route-map
F - Filter-list
P - Prefix-list

D - Distribute is left over -

The opposite is used in the outbound direction
