Re: bgp keepalive & hold timers
by Serge G 10 Dec '22

10 Dec '22

Hi, 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 https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/ref/s…; Nokia also has similar knob) 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. 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.S. I haven't dealt with mailing lists before, so forgive me if I reply to the wrong thread. This is the thread I;m replying to: https://bird.network.cz/pipermail/bird-users/2022-April/016071.html

Setting advmss on kernel routes
by Craig Taylor 06 Dec '22

Hi there, I believe is should be possible (according to the documentation) to set advmss on routes kernel tables. However the syntax/examples for krt_* aren’t clear. I have looked into the mailing list archive/manuals, but have come up with nothing… Please help! CraigT
