In BGP, what is the default value of the keepalive timer?
⚠ Common exam trap
Cisco often tests the distinction between the keepalive timer (60 seconds) and the hold timer (180 seconds), and candidates frequently confuse the two or misremember the default as 30 seconds due to familiarity with other routing protocols like EIGRP.

Correct answer & explanation
✓
60 seconds
In BGP, the default keepalive timer is 60 seconds, as specified in RFC 4271. This timer determines how often a BGP speaker sends Keepalive messages to its peer to maintain the session. The hold timer, which is three times the keepalive interval (default 180 seconds), triggers session teardown if no Keepalive or update is received within that period.

30 seconds
Why it's wrong here
30 seconds is not the default BGP keepalive timer; it is one-third of the default hold timer of 90 seconds, but the standard default is 60 seconds.

60 seconds
Why this is correct
Correct. The default BGP keepalive timer is 60 seconds.
- ✗
90 seconds
Why it's wrong here
90 seconds is not a default BGP timer; the default hold timer is 180 seconds.

180 seconds
Why it's wrong here
180 seconds is the default hold timer, not the keepalive timer.
