Surprised it's not just the higher one!

Definitely 70 seconds, that's what I thought.

Wait, isn't it supposed to be the lower value?

Keepalive timer on B will be 25 seconds.

If I recall correctly, the Keepalive timer on Router B should be 70 seconds since it’s the one configured on that router. But I could be mixing it up!

I’m a bit confused about the Hold Time affecting the Keepalive. Does it mean we just take the lower Keepalive timer from Router A?

I think I practiced a similar question where the Keepalive was determined by the lower timer, so I’m leaning towards 25 seconds for Router B.

I remember that the Keepalive timer is usually set to the lower value between the two peers, but I'm not entirely sure how that interacts with the Hold Time.

I've got this! The active Keepalive timer on Router B will be 25 seconds, since that's the Keepalive timer configured on Router A, which has the lower Hold Time.

I'm a bit confused on how the Keepalive timer is determined when the Hold Time is different between the two routers. I'll need to review the BGP timer configuration rules.

Okay, let me think this through step-by-step. The question is asking about the active Keepalive timer on Router B, so I need to focus on that.

Hmm, this seems straightforward. I just need to remember the BGP timer rules and apply them to the given information.

Wait, there's a Keepalive timer and a Hold Time timer? I thought we just needed to keep the routers happy and well-fed. What's next, a Snack Time timer?

Yes, the Keepalive timer is used to ensure the connection is still alive between the peers.

Router B will have an active Keepalive timer of 70 seconds.

Router A and B have different Keepalive and Hold Time timers.

I'm picking C) 20 seconds. That's half the Hold Time timer on Router B, so it must be the correct Keepalive timer, right? *scratches head*
LA

Correct! The Keepalive timer on Router B is half of its Hold Time timer.

C) 20 seconds

No, that's the Keepalive timer on Router A.

A) 70 seconds

Hmm, this is tricky. I'm going to guess D) 30 seconds, just because it sounds like a reasonable middle ground between the two configured values.

User 2: I agree, it should be 70 seconds since that is the configured value on router B.

User 1: I think the active Keepalive timer on router B will be 70 seconds.
AU

I'm going with B) 25 seconds. Since Router A is configured with a Keepalive timer of 25 seconds, that should be the active timer on Router B.
NI

The answer must be A) 70 seconds. The Keepalive timer on Router B is configured to 70 seconds, so that will be the active Keepalive timer.
OM
Omer

I'm not sure, but it makes sense that the active Keepalive timer on router B would be 70 seconds.
JA

I agree with Jeanice, because the Keepalive timer should be the smaller value between the two routers' timers.
