<div dir="ltr"><p>Hi,</p>
<p>Not sure if it's still relevant, but I just wanted to propose another
approach. Instead of
comparing configured keepalive with the hold timer received from a peer,
it might be more straightforward to add another knob, e.g.
"minimum-hold-timer". (as on Juniper
<a href="https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/ref/statement/minimum-hold-time.html">https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/ref/statement/minimum-hold-time.html</a>; Nokia also has similar knob)</p>
<p>Reason for this is that (the following is just my opinion) 'keepalive' only configures an interval for keepalive messages. And if we start using the value of keepalive timer to enforce some restrictions on peer's hold timer, this may be confusing. <br></p><p>In other words, "minimum-hold-timer" would more clearly indicate our restrictions on hold timers. If I see "minimum-hold-timer 30" in the configuration, I understand that this device has some limitations. If I see "keepalive 10", it doesn't tell me anything about restrictions, only that this device will send keepalives every 10 secs.</p><p>P.S. I haven't dealt with mailing lists before, so forgive me if I reply to the wrong thread.
