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?

Option B looks good, but I'm also tempted by Option D. Maybe the exam designers are trying to trick us with that local preference of 200. Better double-check my work!

Hmm, this is a tricky one. I'll have to draw out the network topology and trace the BGP advertisements to figure out the correct answer. No shortcuts here!

Dean: Definitely, it's all about the BGP route propagation in this scenario.

I think the key is understanding how the route reflector and clients interact.

Given that the routers in AS 65540 are not configured with 'advertise-external', I'd say the expected output would be Option B. R1 should receive only the prefixes from its clients, R2, R5, and R6.

Agreed. R1 will have limited routes in its BGP table due to the 'advertise-external' not being configured.

Yes, that makes sense. R3 will not advertise its prefix to R1 since it's not a client.

I think Option B is correct. R1 will only receive prefixes from its clients R2, R5, and R6.

But considering the local preference of 200 for prefixes advertised by R5, Option A seems more likely.

The question seems straightforward, but I'm not sure if the local preference value of 200 for R5's prefixes is a red herring or a crucial clue. Let's see what the others think.

I agree, it could affect the output of 'show router bgp routes on router R1'.
