Experience running 16.4

I've been running 16.4 on an MX65 for two weeks.  The MX is used I'm my home office and connects as a spoke to our two DCs where the MXs are set up as hubs.  The other MXs all run 15.42 and are stable with no real issues and only the odd alert that doesn't impact user experience.

 

Yesterday the MX65 dropped the VPN connection to the primary data centre and though the connection to the DR data centre was up, all corporate resources were unavailable.  A soft reboot today fixed it for 15 minutes but then it failed in the same way.  Removing the secondary DC didn't help so I ended up downgrading it to 15.42 and it was stable for the rest of the day.

 

Anyone else had any issues with the SD-WAN functionality when mixing 16.4 with earlier release trains?

I've only got one customer running one spoke on 16.4 at the moment using SD-WAN.  No issues so far ... but not a very big sample size.

@PhilipDAth how many hubs does the 16.4 spoke talk to, I'd configured two and it seemed to get stuck when it dropped the connection to the primary and sort of failed over to the secondary but never quite made it.

Re: Experience running 16.4

Charles @cmr , any issues with the MX losing its IP when upgrading to 16.4? Is your device statically assigned or running DHCP?

 

I’ve heard of a device that’s been statically assigned losing its IP and switching over to DHCP after the upgrade.

@UCcert the device I upgraded has DHCP for the WAN so can't comment on that potential issue, sorry.

>how many hubs does the 16.4 spoke talk to

 

THis network has 6 nodes in a full mush configuration (all sites are hubs).

I'm using 16.4 since it came out on a MX67W. I've only configured 3th party VPN connections here, but the connections are stable.
So no error here

 

Edit: The 16.4 has some problems with Meraki Insight. They are working on it already.

Re: Experience running 16.4

I had 16.3 and now 16.4 since its release on a hub with 5 spokes, no issues to speak of related to standard VPN operation. All of the Meraki spokes are running stable releases (14.53), one of the others is a Sonicwall and another is IOS.

16.4 has been solid regarding SD-WAN (lab environment currently) and rock solid with its VPN tunnel to Umbrella.

We have MX84, MX64 and MX64W all running 16.4 for past two weeks or so.  We are seeing some very weird traffic blocking issues across the site to site VPN's since the upgrade.  "Random" blocking of RDP connections which is bizarre.  Opening ticket with Meraki as we can't run like this, definitely considering a rollback.

@RobertDick I was having some issues with 16.4 so rolled back, but so far 16.5 is behaving without issues 🤞

@cmr thanks for the note.  I am getting set up for Meraki support to go have a dig.  Really frustrating at this point.

Re: Experience running 16.4

@cmr I should actually be a bit more accurate in my problem description.  We can RDP across the VPN, we are having problems with RemoteApp connections across the VPN for published apps.  And only for some users not necessarily all, which is making me pull out (remaining) hair.

Re: Experience running 16.4

@RobertDick I had an issue where the connection to the primary hub kept dropping and the connection to the backup didn't properly take over.  Some of the time...
