Topic #: 7
[All JN0-351 Questions]

Exhibit

Your ISP is announcing a default route to both R1 and R2. You want your network routers to forward all Internet traffic through the R1 device

Which BGP attribute would you use?

Show Suggested Answer Hide Answer
Suggested Answer: C

The BGP attribute that you would use to forward all Internet traffic through the R1 device is thelocal preference1.

The local preference is an attribute that is used within an autonomous system (AS) and exchanged between iBGP routers1.It is used to select an exit point from the AS1.The path with the highest local preference is preferred1.By setting a higher local preference for the routes received from R1, you can make R1 the preferred exit point for all Internet traffic1.

I keep mixing up next-hop and local preference. I hope I can remember which one is for outbound traffic!

I practiced a similar question where local preference was the key attribute to control traffic flow. I think that’s what we need here.

I'm a little confused by the wording of the question. Are we trying to prefer R1 over R2, or are we trying to set a default route through R1? I'll need to think this through carefully.

Okay, I've got this. The key here is that we want to forward all Internet traffic through R1, so we need to use the BGP attribute that allows us to influence the routing decision. I believe the answer is local preference.

Hmm, I'm a bit unsure about this one. I know BGP has a lot of different attributes, but I'm not sure which one would be best to use in this scenario to forward all traffic through R1.

This looks like a BGP routing question. I think I need to focus on the BGP attributes and how they can be used to influence routing decisions.

I'll have to go with C) local preference. It's the BGP equivalent of saying, 'R1, you're my favorite. Don't tell the others!'

Local preference, definitely. C) is the way to go. Unless, of course, you want to end up on the router's naughty list. Then you'd use the 'beg for mercy' attribute.

B) next-hop sounds like the right choice here. By setting the next-hop attribute, we can ensure the routers forward the traffic through R1.
