Hi Daan Sorry - I forgot to post back what the issue turned out to be.
We had a power outage in our building where our Dev environment is racked. After doing some tcp dumps on some vxlan interfaces I was seeing lots of bad checksums. Our Network engineer swore that the switches we're all OK but after re-applying the multicast config on the switches - all of the RVR's came back into a stable Master/Backup state across all VPC's. Hope this helps others if they are seeing strange behaviour with VPC RVR's when using VXLAN guest isolation BR Gary Gary Dixon Quadris Cloud Manager +44 (0) 161 537 4980 +44 (0) 7989 717661 gary.di...@quadris.co.uk www.quadris.com Innovation House, 12-13 Bredbury Business Park Bredbury Park Way, Bredbury, Stockport, SK6 2SN -----Original Message----- From: Daan Hoogland <daan.hoogl...@gmail.com> Sent: Friday, April 19, 2024 3:08 PM To: users@cloudstack.apache.org Subject: Re: RVR's in master/master state sorry no one could help you Gary, Have you gotten any further on this issue?
