Router R1 is a route reflector with clients R2, R5 and R6. Prefixes advertised by router R5 have a local preference of 200. Router R3 advertises the prefix 192.168.1.0/27 to routers R5 and R6.
Assuming that none of the routers in AS 65540 is configured with "advertise-external", what is the expected output of "show router bgp routes on router R1?

Wait, no "advertise-external"? That's unexpected!

Definitely expecting to see R5's prefixes listed.

Not sure if R3's prefix will show up on R1.

I think R5's local preference will influence the output.

R1 reflects routes from R2, R5, and R6.

If R5 has a local preference of 200, I think that might influence the routes R1 sees, but I can't recall if R3's prefix will show up in the same way.

I’m a bit confused about how the "advertise-external" setting impacts the routes shown on R1. I feel like I need to double-check that part.

I think I practiced a similar question where we had to determine the best path based on local preference and AS path. I hope that helps here too.

I remember that route reflectors can affect how routes are advertised, but I'm not entirely sure how the local preference plays into the output for R1.

Hmm, this seems like a tricky one. I'll need to think through the board high availability principle carefully.

This seems like a straightforward RAID configuration question. I'll need to weigh the requirements of redundancy and maximizing storage to determine the best RAID type.
