When multiple routing protocols offer a route for the same prefix, what part of the router is in charge of deciding which route to make active?

AThe routing information base (RIB)

BThe routing table manager (RTM)

CThe equal cost multipath configuration

DThe forwarding information base (FIB)

Show Suggested Answer

Suggested Answer: B

The routing table manager (RTM) is responsible for selecting the best route when multiple routing protocols provide a route for the same destination prefix. It makes the decision on which route to add to the routing table based on the administrative distance, metric, and other criteria.

It's the routing table manager (RTM) that decides!

Haha, the router's got a lot of moving parts, doesn't it? Gotta keep them all straight.

The FIB? That's just the forwarding table, not the decision-making part.

Equal cost multipath? Nah, that's just for load-sharing, not picking the active route.

I thought the RTM was in charge of that. Guess I need to study my routing protocols more.

The RIB is the correct answer. It's like the brain of the router, deciding which route to use.

I thought the RIB was where all the routes are stored, but isn't it the RTM that makes the final decision? I need to double-check that.

This question reminds me of a practice question we did on route preference. I feel like the forwarding information base (FIB) might be related, but I'm confused.

I remember something about the routing information base (RIB) being involved in route selection, but I can't recall the details.

I think the routing table manager (RTM) is the one that decides which route to use, but I'm not entirely sure.

I'm pretty sure it's the routing information base (RIB) that's in charge of selecting the active route when there are multiple options. That's a key part of how routing protocols work.

I'm a bit confused on this one. Is it the equal cost multipath configuration that decides the active route, or is that something different? I'll have to double-check my understanding.

I think it's B) The routing table manager. It makes sense to manage routes.

The forwarding information base (FIB) is responsible for determining the active route, right? I'm pretty confident about that.

I feel like C) The equal cost multipath configuration could play a role, but not the main one.

Hmm, I'm not totally sure about this one. I'll need to think it through carefully and review my notes on routing protocols and routing tables.
