IEWB 4.1 Lab1 BGP route-reflector-client

Hi guys,

I just started my lab journey, I'm sorry if I ask any questions that has
been asked before.

I'm doing IEWB 4.1 vol 2 Lab 1 BGP section using dynamips. Although it's not
on the task but I have a question about the route-reflector-client
configuration to clarify my knowledge.

From the topology requirement, R5 is the Route Reflector for R3, R4, R6 for
AS 100. R3 & R6 are connected to AS 54. The task mainly to configure local
preference to advertise from R6 & BB3 link. The question is, why I can't see
the route advertised from R6 with local preference 200 at R4? Is this my
miss configuration or it is how the Route Reflector work? Or is this due to
I'm using dynamips?

Thank you very much for all comments in advance. Any comment is much
appreciated.

Cheers,
rpratikno
