Re: Office 365 Calendar support for macOS Calendar App
Hi Mark, I’m using macOS native calendar app with office365, I just setup as exchange in the add account dialogue. It used to get stuck and refuse to update previous to 13.2, just disabling calendar in the account and then reenabling seemed to fix it, but did take a while, not seen that since recently, I’m on 13.4 now. I only fire up outlook to adjust filters on e-mail.

We always use PeeringDB data and refuse to peer with networks not in PeeingDB ( I think there are only 2 exceptions ) Automation keeps the max_prefix numbers up to date. Our transits we use data from the weekly routing table reports and allow some expansion room. So far this works for us Regards Steve
Re: Long AS Path
Mel,
There was a Cisco bug many years ago that caused lots of issues. Since then we
have limited max-as to 50 and it has not caused any reported issues yet.
Link that does not require a CCO login to view.
