Show Suggested Answer Hide Answer
Suggested Answer: A

BGP add-path is a feature that allows the advertisement of multiple paths through the same peering session for the same prefix without the new paths implicitly replacing any previous paths. This behavior promotes path diversity and reduces multi-exit discriminator (MED) oscillations. BGP add-path is implemented by adding a path identifier to each path in the NLRI. The path identifier can be considered as something similar to a route distinguisher in VPNs, except that a path ID can apply to any address family.Path IDs are unique to a peering session and are generated for each network3. In this question, we have a route reflector (RR) that receives two routes for the same prefix (192.168.0.0/16) from an EBGP neighbor. By default, the RR will only advertise its best path to its clients (R1 and R2). However, we want R1 and R2 to receive both routes from the RR. To achieve this, we need to configure BGP add-path on the RR and enable it to send multiple paths for the same prefix to its clients.

I vaguely recall that leaking routes can be tricky. I wonder if option D is correct since it mentions the 10.1.2.0/24 prefix, which seems relevant here.

I think we practiced a similar question where we had to configure RIB groups. It feels like option C might be the right choice for leaking routes.

I remember we discussed something about static routes in class, but I'm not sure if it's for the 10.1.2.0/24 prefix or the 203.0.113.1/32.

Ah, I see. Moving the web application's scripts and content to a RAM disk could be a good way to reduce the need for swap space. I'll make sure to consider that as a potential solution.

I've got a brilliant idea - let's just tell the hosts at Site 1 to use Bing instead of Google. That way, they won't need any Internet access at all! Problem solved.

Haha, I like the way you're thinking, Dorothea! Why complicate things when a default route will do the trick? Though I suppose the exam wants us to show our routing expertise. Anyway, I'm going with A and D.

Hmm, I'm not convinced. Wouldn't it be better to leak a default route from the inet.0 table to the VPN-A.inet.0 table instead? That way the hosts at Site 1 can access the Internet without having to configure a bunch of static routes.

Hold on, I'm not sure about that. Shouldn't we also configure a static route for the 203.0.113.1/32 prefix? That's the gateway for the Internet, right?
