Hello!
All of our BGP peers have 'prefer older' option enabled. But I noticed that best route is not the oldest one:
Hi
The option 'prefer older' is a bit misnomer, it does not mean the one with the oldest timestamp, but it means 'prefer current best route'.
So if route A was selected first, then route B was updated, and then route A was updated again (so it has more recent timestamp), then route A is still selected.
Thank you, Ondrej. -- Alexander Shikov Technical Staff, Digital Telecom IX Tel.: +380 44 201 14 07 Mob.: +380 50 410 30 57 http://dtel-ix.net/
