Re: Bird setting TTL to 1 at the end of a passive BGP session opening

2022-04-01 Thread Matthew Walster
The setup of the TCP session is handled by the kernel, hence the higher TTL. Once TCP is established, (e)BGP tends to use a TTL of 1 unless it's a multihop session.l, or you're using GTSM. It's expected, and is partly due to the limitations of how sockets are implemented in Linux. M On Fri, 1 Ap

EBGP Multihop TTL vs. TCP accept()

2017-08-16 Thread Matthew Walster
Hello, I've just spent a while trying to debug a BGP session not coming up with bird, it turns out I had mistakenly set the multihop setting to "1" instead of "2" -- my fault. However, the reason it took me so long to realise this error was because the TCP session is established, with default con

s networks, you would do very well to at the very least implement a prefix-limit on the BGP session, that stays "hard down" if it is tripped. Matthew Walster

Optimizing large BGP -> Linux kernel additions/removals

2015-08-17 Thread Matthew Walster
TM_CHANGE or similar in Linux, so the DELROUTE will seemingly cause a tree to either be pruned or re-branched, followed by the NEWROUTE causing a full rebalance run -- whereas a CHANGE would (could) hopefully just over-write the value. Many thanks in advance, Matthew Walster
