Hello Marvin, I need your help in understanding this question.
We have this task and it says at the end that "additional routes could be added in the future. R2 should not advertise any of the additional routes" In this question R2 is receiving routes from R1 and is advertising to other routers. I think answer to this question requires that we should have a route-map statement at the end of the route-map with "no-advertise" community string set. The P.G solution does not have it. Instead it relies on the explicit deny at the end of the route map. In that case R2 will not receive the routes from R1. I think the LAB wants R2 to not advertise the route but it should still accept the routes from R1. Thanks Suresh
